Abstract

Softening occurs when tubular components are subjected to large bending deformations. Two problems associated with the field of impact engineering affected by this phenomenon, viz. the biaxial deep collapse of thin-walled tubular columns and pipe whip, are described. The first involves modelling the bending-rotation relationship for the distributed plastic hinge mechanism formed in the tube. The second addresses the issue of mesh-dependency of the finite difference solution of the governing equations for the dynamic response of a softening beam (pipe).
