Failure prediction in fiber-reinforced composites based on continuum damage mechanics
Paper i proceeding, 2019

The paper presents an approach to intra/inter-laminar failure modeling of fiberreinforces
composites using continuum damage. The intra-laminar damage model is based
on elastic damage, focusing propagation of damage for compression dominated loadings. A
special feature is the study on ply elasticity, induced by graphene enhancement of the polymer
matrix linked to the damage evolution. The results shows that the considered intra-laminar
composite response is only slight affected by the graphene. The open hole compression test
involves mechanisms of both intra- and interlaminar failure. The results show a fairly good
correlation between the experiments and the proposed model.
