Toughness material
WebIn mechanical engineering and materials science, a notch refers to a V-shaped, U-shaped, or semi-circular defect deliberately introduced into a planar material. In structural components, a notch causes a stress concentration which can result in the initiation and growth of fatigue cracks. Notches are used in materials characterization to determine fracture mechanics … WebThus "crack toughness", that is the resistance of the material to crack extension, will be adopted as the definition of toughness of materials in this paper. Crack toughness or …
