Multiaxial fatigue crack initiation in rubber
WebAs most of rubber fatigue experiments are conducted by prescribing certain displacement to specimens, it is considered quite natural to relate fatigue life to strain measures. … WebFracture and Fatigue in Wood - Ian Smith 2003-06-02 Damage in wood is principally the result of fatigue. Fatigue is the process of progressive localised irreversible change in a material, and may culminate in cracks or complete fracture if conditions that initiated or propagated the process persist. Comprehensive understanding of fatigue and ...

Web16 aug. 2006 · Abstract This dissertation is concerned with the multiaxial fatigue behavior of rubber related to pneumatic tires. The results provide the methodologies to predict the fatigue life in the states of complex stresses and for arbitrary geometries by utilizing experimental data from simple stress states on simple geometries. Webmacroscopic fatigue crack initiation necessitates the study of both nucleation and propagation of microscopic flaws. Two main mechanisms were found to occur during …
