nYes, I am using bilinear hardening model.n I have tried yield stress at 500MPa, ultimate tensile strength of 560MPa and Tangent Modulus of 0. In this case, the equivalent stress on the bar seems reasonable as it is like the yield stress. But the maximum principal stress in the rebar seems incorrect as I get very high values (over 1000MPa)nI have then tried yield stress of 500MPa, ultimate tensile strength of 560MPa and Tangent Modulus of 6000 MPa (which is like typical in reinforcement bars). When I do this, the equivalent stress in rebar also goes above ultimate tensile strength (like over 1000MPa) and the maximum principal stress also is very high (over 1000MPa). nnCould you please help with why this is occurring and what I could do? nThanks! n
