Calculating Reserve Factor for Tsai-Wu 3D with continuum shell elements

Hi,

I would like to do a comparison of differend 3D failure criteria for continuum shell elements in Optistruct. Therefore I need to calculate something like the reserve factor or strength ratio for the different failure criteria, because Failure Index can't be compared between different failure theories.

For shell elements I could either us SRCOMPS or calculate it with derived math as shown hear(https://community.altair.com/community?id=community_question&sys_id=f496407a1b2bd0908017dc61ec4bcb7d)

Is there a similar option for 3D Elements, because both don't seems to work for 3D Elements.

Best Regards,
Felix Lentz

    Hi,

    just saw the recently released HW2021.1.

     

    OptiStruct now supports Strength Ratio output for PCOMPLS

    Composite Strength Ratio output for PCOMPLS Strength ratio output for PCOMPLS with PARAM,SRCOMPS is now available.
