Asalamualaikum, I want to verify the Mander nonlinear concrete model using SAP2000. I have taken default material properties of concrete 4000 psi. Then I have made a 6x6x6 inches cube and the technique was to apply load and note down the deformations. Then I have converted Load into stress and deformation into strain. Unfortunately I am getting Linear stress strain graph. Any idea how can I develop stress strain graph by representing concrete compression cube test.
