Abstract

A 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.
