Analysis of structure during explosion

[OscarGaunt]

Hi

I am currently trying to model a concrete panel that experience an exposion load. I want to be able to analyse the sturcture's behaviour under the peak pressure generated by the explosion over time. 

As far as I understand this is done as a Time History Analysis. Is there any information on how to do this correctly? I am sruggling to set it up.

Thanks for your time

Thank you for the quick response!

Sorry but this is for a vehichle collisoin (despite the title of the thread) with different length of times of collision. 

I want to model an explosion with a set length of time, i.e. an explosion that lasts from 0sec to 0.021sec not a explosion thats last for 0.001s then 0.05s then 1sec etc as done with the collisions in the example linked previously.

I have already calculated seperately the pressure as a function of time during the explosion and basically wish to apply this to my concrete panel.

Thanks again for your time

I am afraid you have not read whole mentioned thread.

Read it and calculate required data by your own basing on examples and Pawel's explanations.
