Thermal buckling of P-FGM sandwich beam with porous core on elastic foundation

In the paper "Thermal buckling of P-FGM sandwich beam with porous core on elastic foundation", a coupled effect of thermal and electrical loadings on the thermal buckling behavior of functionally graded material (FGM) sandwich beam resting on Pasternak foundation is investigated. The symmetric multi-layered beam consists of a foam core, two middle FGM layers, and two outer piezoelectric layers. It is assumed that the beam is subjected to a constant voltage and a uniform/linear temperature rise.
