Summary: In the first part of project vibrations of linear and non-linear mechanical systems and their behaviour are investigated. Both numerical and experimental methods are used. Digital simulations of vibrational behaviour of these rigid body systems have been developed. In the second part dealing with shakedown the development of plastic shakedown is carrying out, as well as the methods for calculation of cyclic load limits that can be responded in a purely elastic manner after limited period of the plastic deformations.

Keywords: vibrations of mechanical systems, experimental modal analysis, limit design, shakedown, finite element method

Research goals: First part of these project dealing with vibrations has the goals: - development of numerical simulations for analysis of mechanical systems, linear and non-linear, - investigation of stability of motion and - for the purpose of education of young reserchears the theoretic basis of experimental modal analysis has been written. The part of the project dealing with shakedown has the goals: - evolution of the theory of plastic shakedown in distinction from classical shakedown theory and - evolution of simple methods for calculating the shakedown limits that can be incorporated in general FEM packages. Promotion of three Msc and at least two DPh degrees are exepected during this project.
