How to calculate average strain over element set?

Alberto Perticone

Hi everyone,

I'm facing the titled issue, that is well explained in this formula I'm reporting below:

 

I tried using HyperView, asking for Strain(t) in contour panel and "Absolute Max Principal" as result type. How can I go further? I can't think about a way to do this weighted average over element volumes since I don't have volume information in output. Do you have any idea?

you could use "Result Math' to get something like what you need.

You won't have the summation directly, but at least you could have the product V*result for each element.

One you have the results for all your elements, you could use 'Query' to get a list of all the desired elements.

Hope this helps.

Thank you for your thorough reply, Adriano.

Unfortunately, as I specified before, I don't have available volume output with Ls-Dyna, even tough I load my file.k in the "load model" box...

have you tried the approach I've suggested? Volume is not coming from Dyna. It is coming from element data calculated by HV.

I didn't select "advanced" in the "result-math template" box. Your approach is correct! Many thanks I didn't know it!
