I want to simulate natural and hybrid woven fibre laminated composite by using ANSYS LS-DYNA classic APDL and if can by using ANSYS workbench. Please if do have any suggestion, I would be happy to hear. Thank you

Despite a delayed reply, I'm writing this answer in order to someone may use.

The only element you can use in Explicit dynamic analysis in Ansys-LS-Dyna (Classic APDL), is SHELL163 which is not proper to model composite material for impact analysis. Its too difficult and there is no failure futures like Tsai-wu and etc on it (You need to develop a code for it).

Hi Is there any way for opening LS-DYNA .k file at ANSYS workbench?

I have create .k file using LS prepost. I run the .k file using ANSYS APDL launcher to generate dplot file. My question is, by chance can i import the .k file to Ansys workbench? thank you
