摘要: Abstract This paper reports a successful attempt to apply the theories of fracture mechanics failure impact polystyrene in air. The results show that linear elastic is limited correlating crack initiation data but both maximum load and can be correlated using constant opening displacement criterion calculated from Dugdale model. are supported by similar calculations made experiments with two other commercially important plastics: PVC polycarbonate. toughness these materials PMMA, polystyrene, poly(ethylene terephthalate) compared terms Rice's contour integral, J.
