The present investigation is concerned with the evaluation of the impact toughness of commercial-grade Propylene polymers. Conventional impact static stressstrain and static fracture experiments were carried out. Static stress-strain experiments revealed different pattern behaviors among the materia

The effect of two singularity fields: the HRR solution and a modified form of Rice's solution for the anti-plane shear, on the fatigue crack propagation are investigated. A unified crack growth rate equation is derived involving mechanical, cyclic, fatigue properties as well as a length parameter as
An equation is derived that describes the rate of growth of fatigue cracks under combined static and cyclic stxesses. The equation predicts that a static tensile stress has very httle influence on the rate of growth of fatigue cracks, even ff the static stress is very much larger than the amplitude
