Effective Plastic Failure Strain (epfs) — Ansys Learning Forum

Effective Plastic Failure Strain (epfs)

Hello everyone!

I have a uniaxial tensile test results for my aluminium material. Is it possible for me to obtain "epfs" value for my analysis in ls-dyna?

I have found this formulation, but it looks a bit complex and I don't know how I can find the function Dp.

epspl=integral over time of (depspl)=integral[sqrt(2/3(Dp)ij*(Dp)ij)]*dt

I will be grateful if you can help me.
