To mimic loading and unloading phenomenon using Abaqus I have tried applying load (as displacement, say from 0 to 1mm) in 1st step then in 2nd step I have changed it gradually to its initial value (zero). But, I am not getting expected result in terms of load vs deflection plot. I am getting some amount of residual reaction force at the end of analysis, but I want to free the model from it. Also, when the load is decreasing from its peak value (1mm), for the first increment (decrease in terms of displacement) the reaction force is increasing surprisingly. Please suggest me any procedure to get exact result. Thanks.
