This paper presents a pressure-dependent three-dimensional constitutive law to predict failure for laminated composites. The nonlinear response in shear and the transverse through-the-thickness directions, which is measured experimentally, incorporated directly into model. In addition, secant stiffnesses are dependent on state of hydrostatic pressure general strain. criteria distinguish between matrix failure, fibre kinking tensile failure. In-situ strengths used Propagation takes...
This article showcases the authors’ predictions for Part B of second World Wide Failure Exercise. Predictions are made using failure criteria published in submission A. In several cases, original found to match experimental data well and no revisions made. A novel constitutive model unidirectional composite materials is used improve cases involving multidirectional laminates.
The inherent brittleness of continuous unidirectional fibre reinforced composites is a major drawback to their otherwise outstanding mechanical performance. This paper exploits with overlapped discontinuities at the ply level create significantly non-linear response, due progressive interlaminar damage under tensile loading. Two distinct configurations were manufactured same carbon/epoxy system and tested quasi-static tension, showing that varying thickness length overlapping blocks resulted...
A detailed study of the Mode I interlaminar fracture toughness measure ment multidirectional laminates is presented. The use a novel DCB specimen pro posed in which conventional delaminated along its edges by corporation inserts addition to usual delamination at loaded end. Investigations using this examine +45°/+45° and +45°/-45° interfaces indicate that appropriate width edge can sup press crack jumping fibre bridging occur speci men. Preliminary tests show G IC for are significantly...
This paper presents a computational technique for the prediction of fatigue-driven delamination growth in composite materials. The interface element, which has been extensively applied to predict due static loading, modified incorporate effects cyclic loading. Using damage mechanics formulation, constitutive law element extended by incorporating version continuum fatigue model. details degradation strategy and examples predicted mode I, II mixed I/II are presented demonstrate that numerical...
