Micromechanisms of interlaminar fracture and fatigue

摘要: The interlaminar fracture and fatigue properties of AS/3501-;6 graphite/epoxy are discussed from a mechanistic point view. Particular emphasis is placed on the interaction between loading mode local geometry zone how this affects stresses close to crack tip resulting failure path. Delamination growth under Mode I shown depend likelihood fiber bridging occurring effective these bridged fibers at diverting strain energy away tip. II behavior controlled by both work required shear matrix ease with which tensile can occur.
