Non-linear free vibration of orthotropic circular plates at elevated temperature

Abstract

Non-linear behavior of an axisymmetric orthotropic circular plate at elevated temperature for both clamped movable and immovable edges has been studied. using generated dynamical field equatrons (in the von karman sense) deprived in terms of displacement components. Relative time-periods for linear and non-linear vibrations are seen to depend on relative amplitudes and thermal loading parameter Critical buckling temperatures for both the boundary conditions have been obtained in the limiting case and corresponding results for isotropic plates have been compared with known results.
