Computational-Experimental Investigation of Fracture Toughness in Longitudinal Shear

Longitudinal-shear fracture toughness characteristics have been computationally and experimentally determined for cylindrical and prismatic specimens with a circumferential and edge cracks, respectively. It is shown that during the determination of the fracture toughness characteristic of a finite-t...

Summary:Longitudinal-shear fracture toughness characteristics have been computationally and experimentally determined for cylindrical and prismatic specimens with a circumferential and edge cracks, respectively. It is shown that during the determination of the fracture toughness characteristic of a finite-thickness prismatic specimen under longitudinal shear along the crack front there occurs displacement both in the transverse direction (mode II) and longitudinal one (mode III). This should be taken into account when using specimens of this type.
