i'm getting the equivalent von-mises stress value as zero in explicit dynamic analysis. The material for the flexible attenuator is adiprene and i have kept the shear modulus value for adiprene as zero. The rigid body material is concrete non-linear. I have a doubt does the material adiprene have any issues in afecting my analysis or the mesh quality. If it is so means, somebody suggest me how to improve the mesh quality and bring the result close to the environment as possible.
The distance between the rigid element and the attenuator is 5mm
the velocity is 21000 mm/s in x axis
the end time which i have given is 0.001s
The no. of mesh elements are 15707
The minimum edge length is 2.5
