ABSTRACT

Impact damage to bridges may lead to immense economic losses and significant environmental impacts. Traditional continuum mechanics is in some ways ill-suited to the solving of discontinuity problems in impact damage. The peridynamics (PD) theory has been regarded as a promising method for predicting impact damage. PD has been attractive to researchers as it is a non-local formulation in an integral form, unlike the local differential form of classical continuum mechanics. The hypervelocity impact of cylinders on a rigid boundary test is a classic example to validate the accuracy of the simulation method. In this study, a PD-based 3D discrete particle model of the cylinder impact on a rigid boundary is developed to simulate the process of impact damage. The predictions concerning the damage growth of the cylinder are compared with the previous experiments. The results of the proposed method agree well with the previous experiments.
