Hello all,
I have a concrete cylinder model with Mat 159 CSCM. As shown in the attached stress-strain curve, the curve remains linear up to a point so close to the maximum stress, which is not the normal case in concrete. My question is which parameter should I adjust to control the point at which the strain becomes inelastic?
