Keywords: ACTP, biaxial plastic buckling, mean collapse load, energy absorbed.

Summary

This work, presented in this paper, is based upon the patented mechanical assembly: the "Absorption par Compression-Torsion Plastique" (ACTP). The ACTP transforms a uniaxial external loading into a biaxial one of compression-torsion. Hence, several biaxial loading path complexities are created within the loaded tubes for studying the biaxial plastic buckling behaviour for copper cylindrical shells having a circular cross section subject to further severe loading conditions. An integrity measure of the mean collapse load and the corresponding energy absorbed particularly show the efficiency of the concept used. It is found that the higher the inclination angle (i.e., the higher loading complexity), the greater the rates of change of the torsional component, the greater are the mean collapse load and the corresponding energy absorbed in the tubular structures.
