I create a UHPFRC beam and add the following data to specify it's behavior (Density=2440 kg/m3, Young's Modulus=45000MPa, Poisson's Ratio = 0.21, Tensile Yield Strength=3MPa, Compressive Yield Strength=130MPa, Tensile Ultimate Strength=8.5MPa, Compressive Ultimate Strength=160MPa), and for multi-linear isotropic hardening (strain=0,0.0001,0.0002,0.0003,0.0004,0.0005, stress= 135, 138, 141, 144, 147, 150 MPa respectively) I create a face meshing of 5mm, and for static structure: create a fixed support at bottom left and a frictionless support at bottom right. For the displacement, I create a boundary displacement in the mid top of the model. As a solution, I asked for total deformation and force reaction at the same boundary, fixed support, top face geometry, all of those, but the graph did not like the realistic one. in (figure 1) I have shown all the data that I have inputted in ANSYS The graph that ANSYS draw is (Figure 2) , But in fact I want this graph(figure 3). is there any mistake that I have dine? or any suggestion?
