Sažetak
This work is a reflection of the current status of the attempt to numerically model penetration of a nail into a concrete block. We have accounted for large displacements and strains, effect of the loading rate on the material response and contact detection algorithms. Special care had to be placed on robustness of the contact algorithm since it cannot be predicted what shape concrete block will take during crushing in front of a nail. Large displacement and strain formulation is needed in order to realistically model behavior of concrete on the front of the nail were displacements and strains are large. Dynamic analysis is needed in order to account for the transformation of nail's kinetic energy into strain energy of concrete block (that then causes damage and crushing of concrete) as well as to take into account the influence of inertia forces on the concrete response. Inclusion of the effect of rate of loading will contribute to more realistic description of behavior of concrete under sudden (impact) loading that happen in contact problem.
