【 摘 要 】

The present study is focused on the relation between the microscopic sinusoidal surface morphology and model-1 fracture toughness of carbon reinforced titanium laminates, based on cohesive elements. The interface toughness was computed as a function of geometric parameters of the interface texture. The results suggest that the toughness is increased when wavelength (λ) increase, which provides the need to design fracture/failure resistance materials by carefully selecting the suitable parameters of the interface texture.
