    If I understand right, you should try HyperForm, a Tool that specializes for Forming (or denting), very useful!. 

    You can access it through shortcut folder in Startup menu, choose Manufacturing Solutions folder then  HyperForm.

    There are also some tutorial for you in Help file, Manufacturing Solution tutorial part.

    Hi Ramakiran,

     

    Yes, you can perform oil canning or denting analysis in OptiStruct.

     

    You can use either NLSTAT or NLTRAN with PARAM,LGDISP,1 to define the non-linearities.

     

    The loading and unloading curves can be defined through a TABELS1 card.

     

    Thanks
