The FE model was generated in Hypermesh and run in LS-Dyna with explicit solution.
One of the main goal of the analysis was to find crack distribution under impact area which is depicted in following pictures. So Mat_Winfrith_Concrete (*MAT084-085) were used that that had ability to generate additional binary output database containing information on crack location.
Different number of rows of 0deg and 90deg steel network were used and impact velocity was 4m/s.
