Mode I Failure of Laminated Polymeric Composites

A mechanical model for the prediction of mode I delamination failure of a laminated double cantilever beam (DCB) type specimen is presented. The volume of material ahead of the crack tip that experiences high stresses due to the presence of the crack tip was replaced by a nonlinear elastic spring foundation. The volume undergoing global deformation due to the external loading was replaced by a ...

Failure Mode Predictions in the Compressive Response of Laminated Composites

Of interest in this paper are failure mode interactions when laminated fiber reinforced composites are subjected to compressive loading. Delamination, fiber kink-banding and their interactions are seen to dominate the failure response. This interaction is captured through a computational model that includes interface elements to capture delamination, and, geometric and material nonlinearity to ...

Validation of the Damage Mesomodel for Laminated Composites

The damage mesomodel for laminates (DML) has been developed over last 15 years, particularly at LMT-Cachan [1]. The DML is based on three foundations: 1) Mesoscale – the intermediate scale between the structure (macro) and constituent (fibre, matrix) level degradation mechanisms (micro), 2) internal variable approach – which relates the damage by the degradation of the elastic moduli and 3) Met...

Bolted Joints in Laminated Composites

Expressions were presented which can be used to estimate the strengths of continuous fiber reinforced composite laminates containing pin-loaded holes. The expressions apply to laminates containing either a single pin loaded hole, a single row of pin loaded holes, or two parallel rows of pin loaded holes.

Simulation of the microlevel damage evolution in polymer matrix composites

A 3D Isogeometric Interface-Enriched Generalized Finite Element Method (IIGFEM) is developed to analyze problems with complex, discontinuous gradient fi elds commonly observed in the structural analysis of heterogeneous materials including polymer matrix composites [1]. In the proposed approach, the mesh generation process is signifi cantly simplifi ed by utilizing simple structured meshes that...
