The study of the nonlinear response of sandwich flat panels exposed to
thermomechanical loading systems is the topic of this article. The sa
ndwich structure considered in this article consists of a thick core l
ayer bonded by the face layers, which are assumed to be symmetrically
located with respect to the midplane of the overall structure. The loa
ds involved in this analysis consist of biaxial compressive edge loads
, a lateral pressure, and a nonuniform temperature field. The effects
of the unavoidable initial geometric imperfections and the character o
f tangential boundary conditions are incorporated, and their implicati
ons upon the structural response are explored. In short, the results o
f this study are intended to provide pertinent information on the ther
momechanical load-carrying capacity of flat sandwich structures.
