INVENTOR PROFESIONAL 2013: FEA - Shock / Impact Load Analysis

Hi,

Does the 2013 Inventor profesional embedded FEA have the capability of simulating shock loading?  eg: 25g for 12mili seconds.

Ok thanks.

 

Now for the engineeirng question.  How can you use the frequency modal analysis in FEA, and the dynamic simulation to determine deflection and forces present for the acceleration over time, in order to get an equivalent static force to use in the stress analysis to determine peak stresses?  (obviously some manual calcs would be needed to do this)

 

If this is possible I would then think you could compare this stress with charpy impact material tests based on energy conservation to determine material failure? 

 

Any help greatly appreciated.
