Drilling in carbon/epoxy composites: Experimental investigations and finite element implementation

Optimising curvature of carbon fibre-reinforced polymer composite panel for improved blast resistance: Finite-element analysis

“…The model is able to characterise damage in a composite laminate by employing a stiffness-degradation concept with the help of an element-deletion approach based on the initiation and evolution of damage in the meshed domain [12]. Another damage modeinterply delamination -is simulated using cohesive elements inserted between the adjacent plies of the laminate.…”

“…Here, we adopt a layer-by-layer modelling strategy to capture failure in each ply [12]. This offers several advantages.…”

“…The elastic response of such an interface was modelled using stiffness of CZEs, calculated with an empirical formula suggested by Turon et al [22]. Delamination initiation was modelled using a bilinear traction-separation law with a quadratic nominal-stress criterion [12], while its post-damage response was calculated using a power law [12,22] that accounted for mode-mixity. Detailed description of this can be found in [12].…”

SPH-FEM simulation of shaped-charge jet penetration into double hull: A comparison study for steel and SPS

“…Hence, sandwich plate systems (SPSs) [18][19][20][21][22] with lower density and numerous other advantages, such as enhanced blast and ballistic resistance, has been extensively employed for aerospace and marine applications. Although SPH approaches can be applied to problems with severe distortions, they are generally not as good as the finite-element method (FEM) [23][24][25][26][27] -a mature scheme with a high efficiency, suitable for structural applications. Therefore, alongside the SPH approach, the FEM is applied here to model steel/SPS structures and analyse their damage response, considerable effort was dedicated to coupled SPH-FEM methods [28][29][30][31][32][33][34][35][36][37][38] by various researchers in the past years.…”

Strength prediction for bi-axial braided composites by a multi-scale modelling approach

“…Numerical tools such as finite-element (FE) analysis were used to solve nonlinear dynamic problems associated with composite failure [5][6][7][8][9][10][11][12]. Ivanov et al [7] investigated failure of triaxial braided composites using the degradation scheme of Murakami-Ohno and the damage evolution law of Ladeveze.…”
