Abstract
Craze formation in polystyrene (I) [9003-53-6]-glass bead composites subjected to uniaxial tension was investigated. The bonding between glass and I was varied by using different silane coupling agents. The distributions of several craze formation criteria around an isolated adhering glass sphere in a I matrix were computed using finite element anal. The mechanism for craze formation is fundamentally different for adhering and nonadhering glass beads. In the case of excellent interfacial adhesion, the crazes form near the poles of the beads in regions of max. dilatation and of max. principal stress. With poor interfacial adhesion, the crazes form at the interface between pole and equator. In the latter case, dewetting along the phase boundary precedes craze formation
