Validation and internal length scale determination for a gradient damage model: application to short glass-fibre-reinforced polypropylene

A strain!based transient!gradient damage model is used to analyse and describe the experimentally observed failure process in a Compact!Tension test carried out on short glass!_bre!reinforced polypropylene[ Several aspects regarding the nonlocal character of the damage process in the material are emphasized and the intrinsic length scale is determined using available strain _elds from an experimental analysis[ A good agreement between theory and experiments has been found on a global and on a local level
