suitability of fea software
(OP)
i am designing welded steel structures for trafic security and need to find the stresses involved during impacts. we are a small company and need only to work out the effects of impact forces, is there a cost effective FEA package that you know of? does it work inconjunction with ACAD LT?





RE: suitability of fea software
How precise does your analysis have to be? There are a number of formulas used in shock and vibration analysis to size energy absorbing components based on impact forces. Wouldn't it be sufficient to apply a little analysis to your structure, specify a 2 to 1 or three to 1 safety factor and then use one of the formulas for package design?

thanks for all your help
RE: suitability of fea software
As for reference texts try the "Shock And Vibration Handbook". I don't remember who the author is. It covers a wide range of topics and I'm sure there is something about designing for impact.
Hope this helps.
