    Hi Ramakiran,

     

    You can perform denting analysis using Nonlinear Quasi-Static load step. 

     

    You can create two load steps with loading and unloading conditions. In the second load case which is unloading please keep the LOAD case control command as blank.

     

    Please add PARAM,LGDISP,1 to activate the large displacements

     

    Thanks
