A new $${\varvec{n}}$$th-order shear deformation theory for isogeometric thermal buckling analysis of FGM plates with temperature-dependent material properties

This study presents an isogeometric analysis (IGA) for investigating the buckling behavior of functionally graded material (FGM) plates in thermal environments. The material properties of the FGM plate are considered to be graded across the thickness, and temperature dependency of the material properties is taken into account. A new nth-order shear deformation theory with the von Karman type of geometric nonlinearity, in which the optimum order...
