Determination of Translaminar Notch Fracture Toughness for Laminated Composites Using Brazilian Disk Test

ABSTRACT: This paper evaluates the fracture of notched epoxy matrix composites using the Brazilian disk (BD) test from both numerical and experimental points of view. The study began with a comprehensive experimental program covering three different composite lay-ups (quasi-isotropic, unidirectional...
