Summary: In this paper the flow formulation viscoplastic finite
elementanalysis is applied to metal forming problems where the
materialconstitutive equations are functions of both strain rate andstrain
history. The analysis is carried out in physicalcoordinates under
assumption of small displacement anddeformation theory and stationary
conditions. The numericalprocedures developed include determination of the
particulartrajectory that the strain rate is integrated along, for
eachnumerical integration base point. It is assumed that forstationary
processes the history of the state variables of somepoint corresponds to
their current values at some other point onthe trajectory of the point
considered. Boundary friction istaken into account by developing interface
elements thatdirectly generate the frictional traction at particular
boundarynodes, or impose Coulomb friction conditions as constrains atnode
or edge level using the penalty function approach.Corresponding 2D finite
element routines have been developed andapplied to idealized cold plane
extrusion and other metalforming processes.

Summary: Computational plasticity finds one major application in
metalforming simulations. In analysis of stationary formingprocesses, flow
formulation with veleocity field variables provesvery convenient.
Corresponding finite element algorithms veryefficiently yield strain rate
and stress distributions forcomplex viscoplastic constitutive equations. In
this paper theclassical flow formulation is extended to cases where
thematerial constitution is a nonlinear function of both strain andstrain
rate. A finite element level this extension requires thedetermination of
the trajectory of each numerical integrationbase point in the problem
domain for the purpose of strain rateintegration. Corresponding 2D finite
element procedures have beendeveloped and applied to the idealized cold
rolling process.

Summary: Numerous constructions, such as high-pressure vessels,
cranes,pipe-lines, etc. are subjected to a relative low number ofvariable
loads. Their behavior under operational stressesdepends mainly on
elasto-plastic strains at the fatigue criticalpoints of components (local
strain concept). The optimal designof such constructions requires at the
one side the knowledge of"local stresses conditions", and "low-cycle
fatigue". The paperdeals with some practical foundations of
elasto-plasticbehavior of materials under variable stresses and
roomtemperature, and the procedure of its determination on fewtypical
materials is shown, too.

Summary: This paper presents the results of investigations carried
out todetermine the fatigue life of welded structures with and
withoutresidual stresses under constant and variable amplitudes.
The tests were carried out with longitudinally stiffened flatspecimens
welded to have tensile residual stresses; to determinethe fatigue strength
without residual stresses the specimens were
heat treated and stress relieved. The results show that theresidual
stresses influence the fatigue strength significantlyonly in the case of
high-cycle constant amplitude loads; for allother loading conditions the
influence is not significant.

Summary: In this investigation a systematic "start-from-zero"
approach ofmechanisms has been described and applied to the creation of
anautomotive windshield-wiper mechanism. Following specification ofthe
design goals and restrictions, the potentially usefulkinematic structures
have been generated with aid of graphtheory. A preliminary functional
screening of these structureshas yielded several potentially useful
mechanisms. The typesynthesis was followed by dimensional synthesis,
formulated as anonlinear programming problem. Physical design goals
andconstrains were transformed into the objective and penaltyfunctions and
then optimized. The final result was a proportionedpotentially optimal
mechanism. An alternative approach to thedimensional synthesis of the
generated kinematic structures interms of precision points has been
discussed as well.

Summary: The fatigue life reduction caused by fretting corrosion
wasdetermined in comparative fatigue life tests for axially loadedflat
specimens made of cast nodular iron GGG 40 and hot rolledstructural steel
St 34-2. A special tests ring was constructedfor superimposing fretting
corrosion onto constant amplitude andspectrum loading of the specimen.
Various surface conditions andtwo levels of surface pressure were
investigated. Using theresults of these conditions and two levels of
surface pressurewere investigated. Using the results of these tests and
theparameters derived, comparative damage calculations wereperformed aiming
at predicting fatigue life in the presence offretting corrosion. Means to
avoid corrosion were also explained.

Language: engleski
Summary: The flow formulation approach to viscoplastic finite
elementanalysis of stationary metal forming problems is extended tocases
with strain rate and strain history sensitive material
constitution. Original numerical procedures are developed todetermine
particular point trajectories that the strain rates areto be integrated
along. Corresponding expressions are derivedunder the assumption that the
history of the state variables ofsome point is given by their current
values at other points onthe respective trajectory.
Boundary friction is introduced by having additional velocity-dependent
external load acting on flow elements, and byintroducing a narrow interface
of neutral-behavior elementsgenerating the frictional force on regular flow
elements.
Corresponding 2D finite element routines for materially-nonlinearanalysis
are developed and applied to idealized cold plane strainrolling and
extrusion.

Summary: The flow formulation with velocity field variables is
veryconvenient and efficient for the finite element simulation ofmany metal
forming processes. An original software system isdeveloped for simulation
of metal forming processes in the rigid- plastic FE formulation. Complex
constitutive material modelsare composed by overlaying of simple material
models. The finiteelement procedure used here includes the determination of
theparticular trajectory for each base point within the
viscoplasticdeformation zone. Due to material constitution nonlinearity
thewhole algorithm is iterative. Several distribution of equivalentstrain,
strain rate and stress within deformation zones forprocesses of rolling and
extrusion are obtained.

Summary: An experimental and theoretical investigation of surface
crackgrowth in fillet welded joints under cyclic loading was carriedout.
Surface crack growth is an important problem because mostfailures of large
welded structures originate from surfacecracks. The most frequent cases are
cracks at filled weld toes,but the problem in prediction of fatigue life
growth. Platethickness, crack shape, residual stresses and initial
defectsizes all influence the fatigue performance.

carried out at Fraunhofer Institut furBetriebsfestigkeit (LBF) Darmstadt.
As test specimens were chosenthe non-load carrying longitudinally stiffened
flat specimensdivided in two groups: "as welded" and "stress-relieved".
Withinthe program the residual stresses was determined. As repairmethod the
repair crack grinding and different weldment qualityprocedures were
undertaken. Different postwelding treatments(grinding or hammering) were
analyzed, too. After the specimenswere treated accordingly, they were
loaded again under the sameconditions. The best repair procedure was
determined bycomparing the results of fatigue lives of specimens with
andwithout repair treatments.

Summary: Lot of the crack retardation or crack stopping methods
areanalyzed having their low cost and simple application in mind.The repair
crack grinding and welding methods were primarilyexamined. Different
weldment quality procedures as well asdifferent postwelding treatments
(grinding and hammering) were
analyzed. Furthermore, metal and artificial material
reinforcement methods were studied. Metal reinforcements
(patches) were simple welded, while carbon fibre reinforced
plastic (CFRP) patches were glued over the crack. The"crack arrest holes"
method was analyzed particularlyextensively, because of its good
performance. The effect ofsingle peak overloads on the fatigue crack growth
rate wasstudied as well. Because of numerous parameters thiswork is
dominated by experimental methods.

Date of defense: 12/29/93
Number of pages: 177
Summary: The theoretical concepts of continuum mechanics, the theory
ofplasticity and the solid formulation and flow formulation
aredemonstrated. The basic concept and expressions of the flowformulation
theory are upgraded by originally developedprocedures and expressions for
determination of the strainhistory. In order to mathematically describe the
boundary layerbetween the material and surrounding, specific
numericalprocedures are originally developed to include the
boundaryfriction. Original mathematical expressions and
correspondingelements are derived for direct generation of the
frictionaltraction in the boundary nodes. Alternatively, elements
thatimpose boundary friction conditions in the original formulationas
penalized constrains are derived. The expressions derived arefurther
elaborated in the form of numerical algorithms andmaterialized as an
original program package. Several metalforming processes are numerically
simulated and are compared withthose available in literature.

drilling method

Summary:
SUMMARY
The knowledge of the state of residual stresses is essential for the
determination of the
loading capability, stability and life of the structure. The most
frequently used and
standardized method for the determination of residual stresses is the
incremental hole
drilling method.
The theoretical background and the corresponding expressions are given
which provide
both the analytical description of the problem and a simple residual stress
solution,
excluding their change with depth.
An overview of the geometrical features of the most frequently used
measurement
rosettes and the corresponding methods of calibration is also given.
In addition, the more complex calculations of the residual stress
distribution, using the
FEM for the determination of calibration constants are also presented. The
procedure for
the extraction of material properties from the calibration parameters in
the matrix form
is shown.
The examples illustrate the impact of the assumed mechanisms of gradual
residual stress
relaxation on the final results, depending on the shape of the measured
distribution.
The error occurring in the relaxation strains determination with a
low-cycle drilling and
standard end mills is illustrated by measurements on a known distribution.
Based on these
relaxation strains results (measured), the residual stress distributions
are determined. This
gives a description of the influence of the measurement error on the
particular calculation
method.
