Algoritmy pro stanovení elasto-plastické odezvy konstrukce z elastického MKP řešení

Abstract

Diploma Thesis deals with Algorithms of Elasto-Plastic Structure Response from Elastic FEM Solution. In details is analyzed bilinear material and non-linear Armstrong-Frederick’s model. Attention is also paid to the analysis of available experimental data and literature. In the programming language Matlab is programmed m-file, which sets the upper and lower bound of stress and strain in the notch root Neuber’s and Glinka’s method for both of materials model. The main aim is made macro in program ANSYS APDL, which automatically process the FEM models (the hollow tube speciment and cylindrical speciment) and they determine the upper and lower bound of stress and strain in the notch root by Neuber’s and Glinka’s method, to combine both material’s models.
