Abstract

Finite element procedure is presented for refined transient analysis of two-dimensional (plane or axisymmetric) non-linear structures involving arbitrarily large displacements, rotations and strains. The finite element model is based on the biquadratic nine node element of the Lagrange family. The relevant points pertaining to the equations of motion and their integration and to the spatial description including geometrical and material non-linearities are considered. In particular stress and strain rates are discussed. Finally significant numerical applications show the effectiveness of the proposed method.
