Buckling of axially loaded composite plates with restrained edges

Abstract

Approximate expressions to determine the lowest buckling load of short and long composite plates are presented. The plate is subjected to uniaxial compressive load. All the four edges of the plate are elastically restrained by springs or stiffeners. Explicit expressions for the calculation of the lowest buckling load are presented as a function of the plate’s length. The derived expressions were compared to numerical solutions investigating the entire parameter range.
