Mech.

Governing equations are derived using the classical shell theory and the geometrical nonlinearity in von Karman–Donnell sense is taken into account. Solutions of the problem are established by using Galerkin's method and Runge–Kutta method. Effects of thermal environment, geometric parameters, volume fraction index <em>k</em> and fluid on dynamic critical loads of shells are investigated.</p> ER -
