Abstract
An existing numerical scheme of bicharacteristics for linear-elastic, rectangular plates under in-plane impact loading is extended to plates with curvilinear boundaries. In order to validate the employed concep t, numerical computations are compared with analytical and experimenta l results for plates with circular shaped boundaries. Focusing phenome na induced by reflection and refraction at curved outer boundaries and material interfaces are studied.
