【Abstract】 Large deflection analysis of plates under thermal loading is presented in this paper by using a new effective technique------perturbation differential quadrature method. By introducing the nondimensional temperature and lateral load as the perturbating parameters, a series of linear governing differential equations have been established and then are solved by means of differential quadrature method.更多还原
