Abstract
Transverse matrix cracking can trigger delamination in fibre reinforced graphite–epoxy laminates, which is an important failure mode. Therefore, material models capable of describing transverse matrix cracking are needed for a correct failure analysis of a laminated composite. In this paper an anisotropic damage model is presented. This model is implemented in a finite element code for use in continuum elements. A T300/976 graphite–epoxy laminated strip with a central hole is analysed and the results are compared to experimental results from Lessard and Chang [L.B. Lessard, F.K. Chang, Compos. Mater. 25 (1991) 44–64]. Also the damage behaviour of a AS4/3502 laminate is studied.
