How to get true deformations after static analysis based on the results of an explicit LS DYNA analy

1415user · Mar 7, 2023

Good afternoon, I am practicing Ls-dyna laser shock peening simulation. I perform an explicit analysis in Ansys LS-DYNA and then export the stresses to Static Structural, after solving I get the stress distribution, but I also need a surface deformation profile. I tried to import EPS, but it didn't lead to success. Most likely I'm doing something wrong, could you tell me how to solve this problem?

Thanks for help!

I am not sure I understand the question or the need to export stresses to ANSYS/Mechanical (from ANSYS/LS-DYNA). What is your goal? If the goal is to predict deformation at a steady state, then why not run the explicit analysis a bit longer or use dynamic relaxation or some other method already available in ANSYS/LS-DYNA? By ANSYS/LS-DYNA I mean the native code; not its fancy version in ANSYS/WorkBench. I make that remark because integrating the native general purpose FE code comprehensively is a long-term undertaking.
