I had tried plotting principal stresses also. It also doesn't follow the input values given in the CDP behaviour in Abaqus. I thought that the drucker prager model which is used in Abaqus for CDP behaviour defined the equivalent stress. Hence I compared the mises stress vs total log strain from...
I am testing a reinforced concrete beam in ABAQUS v6.11. I have used CDP model to define my concrete . I have also defined compression and tension damage parameters. My solution has converged and I got a reasonable load deflection curve. But when I plot the Mises Stress vs LE_max, the plot is...
