“…Once an individual ply has failed, the load is shared between the remaining plies which are then, individually, subjected to greater load, and so on until every ply has failed. 2 Generally, composite materials fail due to both intra-and inter-laminar failure. Intra-laminar failure can occur within a single ply as breakage of the fibres, or will take the form of compressive and tensile damage in the matrix.…”

“…These steps are applied repeatedly for each and every failure until the very last ply of the composite laminate fails. 2 It is a recognized phenomenon in Mode II fracture tests that each two neighbouring surfaces remain in contact during the delamination growth until full separation happens. Therefore, the frictional forces can delay the failure (i.e.…”

This study considers the intra-laminar damage mode in composite structures and its effect on delamination prediction. The progressive damage models for matrix cracking and fibre failure in ABAQUS, based on Hashin's model, are only available for shell elements. The results presented here show that the predicted matrix cracking based on the damage model presently available in ABAQUS diverges from experimental results. A new model based on strain failure criteria, which can be used with both shell elements and 3D solid elements, has been developed. The effect of friction coefficient and enhancement factor on the delamination lobes within the delamination area was investigated, and it is shown that the intact zone can be captured in laminate [03/903]s and [903/03]s subjected to low-velocity impact, by using an enhancement factor of η = 0.75, and friction coefficient [Formula: see text], together with the new model proposed here.

“…In our case, a robust strategy, available in commercial software, is required to model damage in the skins and in the plywood core. For the skins, it is now common to use PFA (Progressive Failure Analysis) and the results are often acceptable [20][21][22][23][24]. For the plywood core, a specific approach must be chosen.…”

The impact behavior of innovative wood based sandwich structures with plywood core and skins made either of aluminum or of fiber reinforced polymer (carbon, glass, or flax composite skins) was investigated numerically. The wood based sandwich structures were subjected to low-velocity/low-energy impacts. An explicit nonlinear numerical model based on volume elements with a cohesive layer was developed. A plastic wood law already implemented in LS-DYNA was used in association with composite type damage criteria. Comparisons with experiments in terms of layer deformations and overall contact laws during impact showed satisfactory results.

It has been explored that thin ply would improve the mechanical performances of carbon fiber reinforced epoxy composites laminate. It has not been known whether there are similar effects on thermoplastic composites. In this article, carbon fiber reinforced polyamide 6 (CF/PA6) unidirectional fabrics with two thicknesses of 0.045 and 0.105 mm were used to fabricate the unidirectional laminate (UDL). Tensile and bending behaviors of the UDL were recorded with a digital image correlation (DIC) system, their damage macromorphologies were observed with high-speed camera during loading. The fracture microstructures of the samples were observed with SEM and optic microscope. The results showed that the tensile and bending strengths of the samples with 0.045 mm thick are 79.8% and 24.8% higher than that with 0.105 mm thick. Thinning ply can inhibit the crack expanding, and the time from crack originating to fracture of the sample is larger than that of the thick ply one. Morphologies of the fractures revealed that the crack mainly expanded in the matrix along the loading direction for thin-ply laminate, while the crack developed in the fiber cluster for thick-ply laminate. The results also revealed that the mechanical properties of the laminate can be improved obviously by using thin-ply.
