Numerical simulations of penetration and perforation of high performance concrete with 75mm steel projec
Abstract
In the report, simulations of penetration and perforation of three types of high performance
concrete (HPC) targets are presented and compared with experimental data. The objective of the
simulations was to assess the chosen concrete material model’s ability to predict depth of
penetration or residual velocity. The tests were simulated numerically with the code LS-DYNA
and the standard material type 72, "Concrete Damage". Lagrangian solution technique was used
together with numerical erosion based on a shear strain criteria. For the perforation good
agreement with test data was achieved but in the case of penetration, the results were not
satisfying.
