Numerical simulation of brittle bodies fracture process under impact loading

Numerical modeling of material/structures deformation and fracture under impact loading is complicated problem both in the physical equation formulation and in creating reliable and working algorithms. Previously was presented algorithm for numerical simulation of tensile and shear cracks which based on explicit finite-difference scheme with a local rearrangement of the Lagrangian triangular mesh. It was tested in the problem of influence of detonation products on rock massif. In present article this algorithm is implemented in the application software package called IMPULSE for solving problems concerning with high velocity interaction of solid bodies. There are some examples of calculation of brittle bodies fracture in two-dimensional formulation.
