摘要：

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-fibre-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 fields from an experimental analysis. A good agreement between theory and experiments has been found on a global and on a local level. (C) 1999 Elsevier Science Ltd. All rights reserved.
