Large deflection analysis of skew plates under uniformly distributed load for mixed boundary conditions

Abstract

The present paper deals with large deflection static behaviour of thin isotropic skew plates under uniformly distributed load for various mixed flexural boundary conditions. A variational method based on the principle of minimization of total potential energy has been used through assumed displacement fields. The results are generated for different possible combinations of clamped and simply supported boundary conditions and presented in normalized load-deflection plane. Individual effects of skew angle, aspect ratio and boundary condition on normalized load-deflection behaviour are separately shown.
