Crack Crazing Patterns Interaction Based on Damage Criteria

Abstract:

Article Preview

The present paper deals with the interactions between a main crack and a surrounding layer of crazing patterns. Analysis of the stress field distribution as well as the energy induced during these interactions is based on damage criteria through the resolution of some differential equations conditions and the use of a numerical approach. The effect of amplification and shielding on the resulting stress field is shown through a study of mode I. It is proven, herein, that crazes closer to the main crack dominate the resulting interaction effect and reflect an anti-shielding of the damage while a reduction constitutes a material toughness.
