“…Therefore, several researchers (Krueger 2004;Liu et al 2011;Xie and Biggers 2006;Zeng et al 2016) utilized the VCCT to get the energy release rate, G, to determine the delamination in composite laminates. The main assumption of VCCT is that the strain energy released required for the crack propagation length Δa is equal to that for closing two separate crack surface with crack length Δa (ABAQUS 2016)as shown in Fig.…”

To simulate the progressive failure of pinned joint in quasi-isotropic [0/45/-45/90]s glass fiber reinforced polymer (GFRP) composite laminates used in pipeline, 3-D finite element model is employed in the present work. Hashin failure criterion as a progressive damage model associated with Virtual-CrackClosing-Technique (VCCT) delamination model has been adopted to predicate the failure due to fiber breakage, matrix cracking and delamination in composite pinned joint. This technique may be an innovation for this paper. W/D has been changed to get different modes of failure, i.e. tension, shear-out and bearing failures, in composite pinned joint,. The failure mode for GFRP composite pinned joint has been predicted finally after prediction the failure at each ply laminate of stacking sequence [0/45/-45/90]s. An experimental work of pinned joint in quasi-isotropic GFRP composite laminates has been conducted to validate the present numerical results. The numerical and experimental results showed an agreement between them. Therefore, the present 3D finite element model can be considered as a good candidate to expect the progressive damage in composite pinned joints.

Analytical theories are developed for post-local buckling-driven delamination in bilayer composite beams. The total energy release rate (ERR) is obtained more accurately by including an axial strain energy contribution from the intact part of the beam and by developing a more accurate expression for the post-buckling mode shape than that in the work by Chai et al. (1981) and Hutchinson and Suo (1992). The total ERR is partitioned by using partition theories based on the Euler beam, Timoshenko beam and 2D-elasticity theories. Independent experimental tests by show that, in general, the analytical partitions based on the Euler beam theory predicts the propagation behaviour very well and much better than the partitions based on the Timoshenko beam and 2D-elasticity theories.

“…The growth direction is computed either by using strain energy density (SED) criterion or maximum tangential stress (MTS) criterion (Sih, 1974;Sih & Barthelemy, 1980;Yan, 2006, Aliha et al, 2016aAkbardoost et al, 2014;Mirsayar et al, 2016, Ayatollahi et al, 2006,2011Aliha & Ayatollahi 2008) as no such standard relations is available to compute the crack growth direction based on the relative crack positions. Strain energy release rate based on virtual crack closure technique is developed by introducing an interface element to solve crack growth problem (Xie et al, 2006;Liu et al, 2011). Experimental and finite element studies on mode-I and mode -II crack growth shows good agreement (Maiti & Mahanty, 1990;Lee & Jeon, 2011).…”

An approximated crack growth direction and coalescence of the multiple cracks were obtained for an aluminum alloy plate by the finite element approach (FEA). Self-similar as well as nonself-similar crack growths were observed based on relative position of multiple cracks. The FE predictions of crack growth direction are validated with an experimental results and good agreement is established. Typical numerical results are presented to examine the effect of changing the crack tip distance (S), crack offset distance (H) on crack growth direction and coalescence of a finite aluminum alloy aluminum plate. Based on the analysis and experimental results, a new mathematical models for self-similar and non-self similar crack growth are introduced.
