Summary: This paper discusses the issues involved in the development
of combined finite-discrete element methods; both from a fundamental and
theoretical viewpoint and some related algorithmic considerations essential
for the efficient numerical solution of large scale industrial problems.
The finite element representation of the solid region is combined with
progressive fracturing, which leads to the formation of discrete elements,
which may be composed of one or more deformable finite elements.
The applicability of the approach is demonstrated by the solution of a
range of examples relevant to various industrial sections.
Keywords: Finite-Discrete elements, Prograssive fracturing, Deformable finite elements

Summary: The contact surface, with its accompanying load transfer,
may well constitutive the critical factor in a structural member. Thus it
is essential to be able to perform contact stress analysis of a component
accurately and efficiency. Considerable research effort is represented in
the literature for contact analysis using finite elements. To obtain
reliable results in the contact zone, it is necessary to provide a very
fine discretization in that zone. Many distinct contact zones may exist,
which may force the entire domain, and not just the contact zones, to be
discretized finely. This generally leads to an excessive number of degrees
of freedom (dof), resulting in an uneconomical, and sometimes intactable,
analysis. The boundary element method (BEM), which dealswith the
discretization of only the boundaryof the structure being analyzed, may be
used to circumvent these difficulties and provide accurate, economical
results. While a fine discretization of the contact zone is still
unavoidable, the BEM leads to a smaller number of dof's because the rest of
the boundary need not have a fine mesh. The problem of frictionless contact
between an elastic body and a rigid surface is formulated as an
optimization problem. Three distinct functions are defined in terms of the
unknown variables (displacements and tractions) corresponding to the
contact surface, and exprssed as quadratic objective functions that are to
be minimized. The solution is obtained using the standard quadratic
programming techniques of optimization. A number of example problems with
straight and curved boundaries were solved. The present formulations were
validated through comparison of the test problems with existing alternative
solutions.

Summary: A novel algorithm for the analysis of contact problems in
elasticity has been presented in this paper. The algorithm is based on the
boundary element method and a direct approximation of the contact
complementarity using linear programming. An incremental loading scheme has
been developed to ensure an accurate approximation of the deformation path
that the object experiences during the process of contact. Several
numerical examples have been analysed to illustrate the validity of the
proposed formulations.

Summary: A contact surface design technique, based on a linear
programming formulation that was originally developed for the finite
element method, has been extended to contact problems modeled using the
boundary element method. The design optimization is driven by the
minimization of peak contact traction that is a primary variable in the
boundary element method. The contact of an elastic body with a rigid
surface is considered. The schemes for the modification of the geometry of
both the rigid surface and the elastic body are proposed. The solutions of
example problems are presented to demonstrate the validity of the present
formulations.
