hi..the finite element analysis to be performed in a staged manner ..so you need to define the execution of the problem in stage wise analysis i.e. first create model, then apply loading in the second stage in term of number of loading and in third stage unloading to be performed in number of load step.. by doing in this manner, you could study the response of materials at different stage..ok all the best..

kindly dear
