Hi Peter,

So it's a very flexible material. But I can't understand the reason of differences in  the results of the Silicone rubber using Ansys engineering data and what I defined with E=1.9 GPa  and Density= 1250 kg/m*3 and Poisson  ratio= 0.495.

For the higher Young's modulus (1.9GPa), reults are not symmetric while in the flexible one (1.8Mpa) are fully symmetric:
