Illustration of the Interaction of Strain and Displacement Nonlinearities in the Structural Tangent Stiffness

Abstract

Systematization of complex nonlinearities, the wide-ranging linearization concepts are detailed in [3], [4] related to material, strain, displacement and loading type nonlinearities and their interaction. In this paper, an illustration of the full geometric nonlinearity, the interaction of the strain and displacement nonlinearities are presented, by means of the finite element model of the Timoshenko beam.
