Development of computational models in phenomenological pasticity
Project goals
This project aims at substantiation, refinement and further development of recently proposed models of directional distortional hardening to reach the stage of practically applicable theory, which may be employed to solve real-life problems of elastoplasticity and engineering in general. In particular, these goals consist in specification of models material parameters, experimental calibration of associated constants in terms of analytical solutions to the fundamental modes of deformation, such as the tensile tests, ratchetting, etc. and numerical implementation of the governing equations in the framework of the finite element computer code. The constitutive models considered should be later extended to materials sustaining loadings under very large strains with the inclusion of FE-coding mentioned before.

Project results evaluation
Investigation was made into material parameter identification of the models with directonal distortional hardening, their numerical implementation in the context of the finite element method, and application to multiaxial ratcheting problems and cyclic load phenomena. Paper on the calibration of the model´s parameters and on the numerical implementation have been finished.
