Abstract:

A finite element computer code is under development which is specialized to strong nonlinearities of the geometrical type. The work includes beam and shell elements, and makes use of three important technical features to best address the nonlinear problem. These are 1 the use of higher degree functions for the membrane or axial displacements than for the bending displacements 2 the use of the static perturbation method and 3 the use of Euler angles to represent rotations. Computed results illustrate the methods and computer codes developed. Author
