I am working on impact analysis of brittle material on a metal substrate. I am using Johnson Holmquist damage material model. For meshing, I am used 3D stress element (C3D8R) defined the mesh control and element deletion option 'YES'. I have used the boundary condition as symmetric (as the model is an axisymmetric model). In the visualization, the elements in the particle is distorted weirdly (as shown in image). Any insights about how to resolve this issue.
Thanks in advance!
