“…As seen by the results in Table 2, a substantial agreement is obtained with the predictions of [37], although in some cases the discrepancies can be non-negligible. For instance, the Ritz results relative to the [± < 15|75 > x ] 4 lay-up are higher with respect to those of [37], irrespective of the kinematic theory. For this reason, Abaqus analyses were performed, demonstrating, on the contrary, very close agreement.…”

“…A second test case is taken from [37], where the thermal buckling analysis is presented for variable-stiffness plates subjected to restrained pre-buckling thermal expansion and simply supported boundary conditions. The material properties are those of an orthotropic material, whose non-dimensional thermoelastic parameters are given as: 4 , where the angles are measured with respect to the x-axis, and the variation is linear with x.…”

“…Recently, the thermal buckling behaviour of variable-stiffness plates was investigated in [36], using a thin-plate finite element formulation, and [37], by considering FSDT. Thermally induced multi-stable configurations were assessed by Haldar et al [38] using finite elements and the Ritz approach proposed by Dano and Hyer [39].…”

The possibility of designing composite panels with non-uniform stiffness properties offers a chance for achieving highly-efficient configurations. This is particularly true for buckling-prone structures, whose response can be shaped through a proper distribution of the membrane and bending stiffnesses. The thermal buckling behaviour of composite panels is among the aspects that could largely benefit from the adoption of a variable-stiffness design, but, in spite of that, it has rarely been addressed. The paper illustrates a semi-analytical approach for evaluating the thermal buckling response of variable-stiffness plates (VSP) by considering different boundary conditions. The formulation relies upon the method of Ritz and a variable-kinematic approach, leading to a computationally efficient implementation, which is particularly useful for exploring the larger design spaces, typical of variable-stiffness configurations. Due to the possibility of choosing the underlying kinematic approach as an input of the analysis, the formulation is not restricted to thin plates, but is suitable for analyzing the response of thick plates as well. Novel results are derived, which can be useful for benchmarking purposes and for gathering insight into the mechanical behaviour of variable-stiffness plates. Furthermore, the importance of transverse shear flexibility is illustrated with respect to the boundary conditions as well as the degree of steering of the fibers.

This statistical and numerical study deals with buckling temperature behavior of laminated composite plates with central circular and semicircular holes. Numerical buckling temperature analyses were performed using finite element software ANSYS based on Taguchi L18 orthogonal array. The plates were designed from graphite/epoxy systems. Fiber orientation angles and cutout shapes of the plates were assumed to be the control factors. Analysis of signal-to-noise ratio was used in order to investigate of the effects of fiber orientation angles and cutout shapes on the critical buckling temperature of the plates. Also, analysis of variance was performed in order to see percentage contribution rates and significance levels of control factors.
