Abstract

Abstract

This paper studies large deflection problem of beam and plates by the finite element method. The elongation of the middle surface caused by its rotation is considered in strain-displacement relations. The higher order terms will be reserved when strain energy is calculated. The elastic stiffness matrix, linear and nonlinear initial stress stiffness metrices are derived by the principle of minimum potential energy. Examples show that precision will be properly manifested although the total storage amount and the calculating lime are not increased. The iterative method with co-moving coordinate must be adopted to avoid parasitic rigid body motion.
