Parametric effects on embedded delamination buckling in composite structures using the EAS three-dimensional element

On computational modeling of postbuckling behavior of composite laminates containing single and multiple through-the-width delaminations using interface elements with cohesive law

“…Their developed analytical method is based on the first order shear deformation theory within the framework of Rayleigh-Ritz technique. Park and Lee [9] performed a parametric study on the buckling behavior of laminated composites containing embedded rectangular delamination. They proposed a 3D element with enhanced assumed strain (EAS).…”

Experimental and simulation study of the effect of cut-out defect in carbon fibres twill weave composite

“…Other researchers have applied finite element method (FEM) using a cohesive element to validated their results and growth in thin laminated composite with embedded flaws under compressive load [10]. It was concluded that the effects of flaws on bending in composite laminate is greatly depend on specimen length-width ratio, flaw shape, flaw size, and flaw depth in the specimen [11]. Also, researchers performed a crack growth analyses on composite panels containing embedded flaw using a geometrically non-linear FEM software, based on explicit dynamics model [12].…”

Stability analysis of delaminated composite beams

“…The EulereBernoulli beam and classical lamination theory were used together to develop an innovative analytical approach in order to obtain the buckling load of a delaminated composite beam by Wee and Boay [10]. Park and Lee [11] studied the buckling behavior of laminated composite structures containing an embedded rectangular delamination using the enhanced assumed strain threedimensional element.…”
