    nonlinear analysis for permanent set

    Jong Lee

      Hi,  I ran a nonlinear analysis of a window system with reinforced metal in the mid span with the time-load curve of 10 sec loading, 10 sec unloading and 50 sec relaxation to get permanent set.  The analysis failed after load was removed in total 70 sec. Must I provide curve for stress relaxation in the analysis? Also time step seemded have trouble finding proper values.  Jong
