Hi All,

 

I am trying to input my own biaxial test data (stress and strain) into EngineeringData, but I found that the unit for strain in the interface is mm^-1. Shouldn't the unit for strain is mm/mm or in/in....?

Another question is, is there anyway to perform curve fitting for some anisotropic materials? I saw the material models that are supported in ANSYS to do curve fitting are mostly isotropic hyperelastic. 

Thanks!

You are correct and if you look closely there is a space between m and m^-1 ....so this m/m....if you change the units to mm...it would look mm mm^-1 or in other words mm/mm

Also, we don't support curve fitting anisotropic materials, it's a elaborate process and has to be done outside ANSYS

Understood! Thanks.

Hi,nI would like to know if this strain is supposed to be engineering strain?nThanks,nWikin
