Thanks for replying...i meant solid 65 and i wrote the compressive stress strain curve only and the parameters (max fcu-max tensile-coff of open and close shear)..i dont know how yo define failure criteria on ansys and i made a lot of supstep like 1000 step and the solver go on the end but when i check the stress on the bottom and upper face... i use displacement force face i see just tensile stress as i wrote on command file
