Abstract: In this paper, the damage zone development and damage evolution ahead of a crack tip in High-Impact Polystyrene (HIPS) specimen are studied from the viewpoint of Continuum Damage Mechanics. The damage distribution and tensile stress in the damage zone, and the damage zone length and opening displacement are calculated based on a modified Dugdale model and a damage evolution law for HIPS. Also, the interaction between the crack and microscopic material damage is discussed. It is found that the material damage has a great influence on the damage zone development and crack initiation.
