Thermal buckling analysis of cross-ply laminated plates using a simplified HSDT

What is it about?

This work presents a simplified higher order shear deformation theory (HSDT) for thermal buckling analysis of cross-ply laminated composite plates. Unlike the existing HSDT, the present one has a new displacement field which introduces undetermined integral terms and contains only four unknowns. Governing equations are derived from the principle of the minimum total potential energy. The validity of the proposed theory is evaluated by comparing the obtained results with their counterparts reported in literature. It can be concluded that the proposed HSDT is accurate and simple in solving the thermal buckling behavior of laminated composite plates.

Why is it important?

In this paper, a hyperbolic shear deformation theory is employed to develop the analytical solution for the thermal buckling analysis of cross-ply composite multilayered plates under uniform temperature rise. The present theory differs from other higher order theories because, in present theory the displacement field which include undetermined integral terms and contains only four unknowns which is not considered by the other researchers.
