Abstract:
The research work on this project has been concerned with dynamic effects on fracture. Two main areas have been investigated high-rates loads on bodies containing cracks, and fast fracture and crack arrest. Dynamic effect become important if the external loads give rise to propagating mechanical disturbances as for impact loads and explosive charges which can strike a crack and cause crack propagation. Spalling is an example of a fracture phenomenon caused by the rapid application of loads. Dynamic effects become also important if a crack propagates very rapidly, so that rapid motions are generated in the solid. Even though in most cases fracture studies should focus on despite the best attempts for prevention. JES
