“…This can be taken care of by variationally incorporating [29] its effect through [K c ]. While investigating the bending and buckling behavior in hygrothermal environment, the stress-strain relations are modified incorporating the thermal and moisture coefficients [27]. The studies of Singha et al [31], Nath and Shukla [32], and Shen [33] may also be referred for details.…”

“…It was also found that with increasing moisture concentration, the mechanical buckling loads linearly decrease which is more pronounced in thin plates. Sreehari and Maiti [21] developed a finite element formulation to investigate the buckling and post-buckling of composite plates subjected to mechanical loads and hygrothermal environments. They examined the buckling response of the structure for different geometrical parameters, moisture content, and temperature employing an inverse hyperbolic shear deformation theory.…”

The present work attempts to investigate the influence of hygrothermal environments on the buckling of soft-core sandwich plates with laminated composite face sheets. The stability equations are derived based on piecewise low-order shear deformation theory (PLSDT) and then solved using different methods, depending on the boundary conditions. For fully simply supported sandwich plates, an analytical method is developed which results in some closed-form solutions. For sandwich plates with two parallel simply supported edges and two clamped edges, a semi-analytical solution is established using one-dimensional generalized differential quadrature (GDQ) technique. Finally, for fully clamped sandwich plates, twodimensional GDQ approach is applied to the governing equations. To validate the results of proposed methods, a comparative study with various examples is carried out verifying that the methods in the present work can accurately predict the buckling load of sandwich plates in hot and wet environments. Then, a comprehensive parametric study is performed to show the effects of temperature and moisture content on the buckling of sandwich plates for different parameters such as length-to-thickness ratio, core thickness, and boundary conditions. It is concluded that both temperature and moisture content have significant influences on the buckling behavior of sandwich plates.

The impacted buckling problems of the slender composite column have a particular essential engineering meaning for the civil engineering, mechanical engineering, and nuclear power engineering fields. Specifically, the contact duration time and buckling time are of importance to design nuclear reactor. This paper mainly concentrates on the dynamic buckling of a slender composite column subjected to a sudden axial load in a hygrothermal environment. In this study, the distribution of strain of the column is considered nonuniform. The humid and thermal factors are taken into account in the stress–strain relation. Employing the composite material's constitutive relation, the buckling governing equation of the composite column can be obtained. The Galerkin method and Laplace transform are applied to solve the buckling problem of the composite column. In this process, the contact duration time and the buckling time are two significant parameters that are typically considered in this research. In the numerical section, the present solutions are validated by comparing to the result in published research. The effects of the kinetic energy of the impactor, geometrical features of the column, and hygrothermal factors on the buckling solutions are studied as well.
