In the present paper, crack initiation in mixed-mode (I+II) fracture has been studied using notched circular ring specimens. A new criterion of brittle mixed-mode (I+II) fracture based on the notch tangential stress ...

In a composite material reinforced by short random fibers, damage results from different elementary failure mechanisms such as matrix micro-cracking, fiber pull out, failure of fiber/matrix interface, failure of fibers, ...

Delamination in the multidirectional laminates under bending loading is often difficult to characterize because of problems involved by excessive deformations ahead of the crack tip and by non-linearities due to large ...

This paper presents the energy analysis of static mode III fracture of thin steel sheets. For dynamic tearing studies we used the Charpy test apparatus. Static tearing tests performed on three kind steel sheets indicate ...
