Hi

I am looking to output the overall strain of a laminate in FEMAP.
Looking to either get the max ply strain of the overall strain in FEMAP interface

When i request strain output it gives me the strain for every ply how do I get it for the overall laminate ?

Going off FEMAP memory from long ago, I think you can get shell element surface strains.

But ply strain and laminate strain is the same (unlike stresses), since strain is linear thru the thickness. The surface ply strains will be the largest values, for the directions of that those plies.

You might want to post this question in the FEMAP forum. (and delete it here)
