Hello,

In my research I am trying to simulate an epoxy (Poisson ratio of epoxy is about 0,3 and Young modulus = 3 GPa). So during calibration with tensile test I faced a problem: axial Poisson's ratios Poisson_YY and Poisson_ZZ are too different.

Is it correct to use average Poisson ratio for calibration (Poisson_ave on picture) or am doing something wrong?

I guess that you can improve the accuracy of your results by unclamping the "Boundary-xMin" set. The discrete element must be free to move in the Y and Z direction to match a perfect uniaxial tensile test.

Kind regards, Damien.
