The thermomechanical buckling and postbuckling behavior of layered composite
shell type structure are considered with the finite element method (FEM)
under the combination of temperature load and applied mechanical loads. To
account for through-thickness shear deformation effects, the thermal
elastic, Higher-Order Shear deformation Theory (HOST) is used in this study.
The refined higher order theories, that takes into account the effect of
transverse normal deformation, is used to develop discrete finite element
models for the thermal buckling analysis of composite laminates. Attention
in this study is focused on analyzing the temperature effects on buckling
and postbuckling behavior of thin shell structural components. Special
attention in this paper is focused on studying of values of the hole in
curved panel on thermal buckling behavior and consequently to expend and
upgrade previously conducted investigation. Using FEM, a broader observation
of the critical temperature of loss of stability depending on the size of
the hole was conducted. The presented numerical results based on HOST can be
used as versatile and accurate method for buckling and postbuckling analyzes
of thin-walled laminated plates under thermo-mechanical loads.
