Quasi-statyczna sprężysto-lepkoplastyczność dla materiału nieściśliwego. Rozwiązanie MES

The finite element method has been applied to quasi-static elasto-viscoplasticity with kinematic hardening. Incompressible material in the elastic range has been considered for the Poisson ratio close to 0.5. The substantial influence of the Poisson ratio on deterioration of the algorithm effectiveness in the range of stability and accuracy was not observed. The satisfactora result for the incompressible material with application of parametr Theta=1 and the Poisson ratio ni=0.495 has been obtained.
