“…: the deflections of the top and bottom part of the delaminated plate portion are independent) results in physically inadmissible mode shapes, where the top and the bottom parts can intersect each other. Therefore even the calculated critical amplitudes will be wrong (Mujumdar and Suryanarayan, 1988;Shu and Della, 2006;Kharazi et al, 2014;Guo et al, 2014;Wang and Tong, 2002). Avoiding this phenomena a constrained model is introduced in this paper, where the deflection of the delaminated top and bottom parts is the same Eq.…”

“…Experiments on multiple delaminated composite plates and a FEM study using ANSYS was carried out by (Aslan and S ßahin (2009)). Kharazi developed a layerwise theory based on the First-order Shear Deformation Theory (FSDT) where the prevention of the penetration of the delaminated layers was solved by using the penalty method, and artificial springs (Kharazi et al, 2014). The mixed-mode buckling was captured with a contact model in the paper (Hwang and Liu, 2001).…”

a b s t r a c tIn this work we analyse the buckling process of composite plates with trough-the-width delamination and straight crack front applying uniaxial compression. Local, global and mixed mode buckling cases are considered. The novel part of this work is that the distribution of the resulting in-plane forces is taken into account for the analysis of the buckling of the delaminated plate portions. For determining the behaviour of the delaminated plate with respect to the external compression, first an analytical method is given for determining the global critical loads. Second the local critical forces are determined using a finite element model. For this analysis a semi-discrete element was developed for the delaminated plate portions. The analysis was carried out using the method of harmonic balance because of the distribution of the in-plane forces along the delamination front. The buckling process of the plate with respect to the axial compression is determined from a displacement controlled model.

In this study, a finite element based formulation is developed for analyzing the buckling and post-buckling of composite laminates subjected to mechanical and hygrothermal loads using Modified Hyperbolic Shear Deformation Theory (MHSDT). The changes in the critical buckling load are presented for different lamination schemes, thicknesses, material properties and plate aspect ratios. In addition, post buckling analysis is performed for a composite plate subjected to uniform in-plane thermal and moisture induced loadings by using MHSDT. Matlab software has been used for programming the analysis. The results obtained by Matlab codes are in a satisfactory consistence compared to the references. Thus, the developed MHSDT has been validated for buckling and post buckling analysis of laminated plates in hygrothermal environment.

“…Fazzolari et al [9] developed an exact dynamic stiffness element based on higher order shear deformation theory and extensive use of symbolic algebra for the first time to carry out a buckling analysis of composite plate assemblies. Kharazi et al [10,11] studied the buckling behavior of the composite laminates by using different plate theories and they improved their work with developing a novel Layerwise theory based on First Order Shear Deformation Theory (FSDT). Mantari et al [12] developed a new higher order shear deformation theory for elastic, composite/sandwich plates and shells.…”

“…[11]) to the higher orders and uses them to investigate the consequences of different geometrical parameters of the delaminated area, lay-up sequences and thickness of the laminate on the deflection of a composite plate containing through-the-width delamination under buckling condition. The formulation is obtained on the basis of Rayleigh-Ritz approximation technique.…”
