Abstract
The work is aimed to the numerical modeling of low-velocity impact and validation of the hyperplastic material model with damage designed by authors for modeling of woven composites and implemented into commercial FEM software Abaqus. The woven composite plates were subjected to the low- velocity impact by usage of the drop-test machine with two types of impactor differed by the weight. The experimental data of the tested composite plate in form of deflections at three selected measurement points and the contact force – time dependencies were compared for particular impact velocities with the numerical simulations. The visual comparison of the occurrence of damage on the composite plates was performed and compared with corresponding damage results obtained from the computational model
