The time dependence of fracture has two sources: (1) the viscoelasticity of material behavior in the bulk of the structure, and (2) the rate process of the breakage of bonds in the fracture process zone which causes the softening law for the crack opening to be rate-dependent. The objective of this study is to clarify the differences between these two influences and their role in the size effec...

Data for fracture in human humeral cortical bone are re-analyzed to assess the validity for this material of linear-elastic fracture mechanics (LEFM), which is the standard method of analyzing toughness and one basis for analyzing clinical data relating to bone quality. A nonlinear fracture model, which is based on representing the damage zone in the bone by a cohesive model, is calibrated agai...

Interface delamination is the major weakness limiting diamond coating tool performance in machining. Thus, quantitative characterizations of the interface behavior are important to better understand and design diamond coating tools. In this study, we attempt to apply a cohesive zone model to investigate the coating-substrate interface behavior. The cohesive zone model is based on the traction-s...
