Evaluation of Chaboche parameters using CPFE simulation in PRISMS

[SAYANTAN DAS BANIK]

Hello Everyone,

I am a beginner in the field of CPFE simulation and its aspects and recently started learning PRISMS code and its implementation. I had following doubts:

1. Is it possible to evaluate chaboche parameters accurately related to cyclic plasticity modelling using CPFE simulations in PRISMS? Is there any paper related to this.

2. How much efficient (and possible from running time constraint) is CPFE simulation to predict the cyclic transient behavior (i.e. before loop stabilization) which becomes important for materials like Austenitic Stainless Steel which never stabilizes even after very large cycles.

Regards,

Sayantan
