Impact and explosion analysis in LS-DYNA

[Kalani Ranasinghe]

Dear all,

I would like to ask if it is possible to analyze the combined effect of both impact and explosion, using a mortar or bullet that causes both mechanical impact and explosive detonation upon contact.  

Thank you,

Kalani

I assume by “combined effect” you mean the explosive should “self detonate” upon impact?

 

Then the simple answer is Yes.

 

However, this will require the use of the keyword

*EOS_IGNITION_AND_GROWTH_OF_REACTION_IN_HE for which there is very little data available in the open literature.  Some information about this keyword is available from the two manuscripts linked below:
