000013764 520__ $$2eng$$aA complex dynamic plastic buckling of thin tubes made from 316L stainless steel is experimentally investigated showing their energy absorption capacity. Initially proposed [1] for quasistatic and [2] for dynamic loadings, the novel idea, which aims to enhance the strength properties of materials, is extended for studying the biaxial plastic dynamic buckling behavior of circular shells. It can be assumed that changes in local deformation mechanisms, which reflect this enhancement in the strength properties, are mainly governed by the loading path complexity. The question of whether the performance of dynamic axially crushed tubes could be further improved by using a new developed device (the ACTP: Absorption par Compression-Torsion Plastique) generating a biaxial loading path (combined compression-torsion) from a uniaxial loading. A key point emerging from this study is that the structure impact response (i.e., the plastic flow mechanism and the absorbed energy) is influenced by the loading rate coupled with the biaxial loading complexity. In this study, different biaxial loading complexities provided by the ACTP are extensively investigated. The obtained results show that the higher biaxial loading complexity provided by the ACTP is applied; the greater is the energy absorbed by 316L stainless steel structures..
