Hello Team,

I would like to apply the shock load of 3 cycles of 25G on the Battery. If any one is having any sample model which you have defined, could you please share here?

I am stucked doing this procedure in LS Dyna. Earlier I have done that in Optistruct. 

Thank you in advance.

Hello, you can use *LOAD_BODY_X (or Y or Z depending on the loading direction) to apply the forces due to the prescribed acceleration history. The acceleration history will be defined through the LCID curve of the *LOAD_BODY keyword. Acceleration units consistent to the mass units should be used.

Hi Andreas,

Thank you for your inputs! After trying different options, I used *LOAD_BODY_Z to apply the shock load. It is working.
