... of both quasistatic and dynamic tests. The validated model is used to study the crushing characteristics of tubes with multiple induced circular hole discontinuities using the finite element package ABAQUS/EXPLICIT version 6.4-6. Holes of diameter 17 mm are used as crush initiators, which are laterally...

... dynamic and quasistatic axial crushings are performed. The mild steel tubes are 350 mm in length, 50 mm wide, and 1.5 mm thick. Circular hole discontinuities, 17 mm in diameter, are laterally drilled on two or all four opposing walls of the tube to form opposing hole pairs. The total number of holes...

...Dirk Mohr; Tomasz Wierzbicki This paper deals with the evaluation of the crashworthiness of thin-walled sandwich box structures for automotive applications. Quasi-static crushing simulations are carried out to estimate the energy absorption of prismatic box columns made from sandwich sheets...

...Denzil G. Vaughn; James M. Canning; John W. Hutchinson The plastic buckling of columns is explored in a regime where plastic wave propagation and lateral buckling are nonlinearly coupled. Underlying the work is the motivation to understand and quantify the dynamic crushing resistance of truss cores...

.... At the macroscopic level, different characteristic regimes are identified in the measured shear and normal stress-strain curves: elastic I, elastic II, nucleation, softening, and crushing. The first elastic regime shows a conventional linear elastic response, whereas the second elastic regime is nonlinear due...

...T. J. McDevitt, Mem. ASME; J. G. Simmonds, Fellow ASME Load-deflection curves are computed for an elastic-plastic ring that is slowly crushed between frictionless, rigid plates (platens). The ring is assumed to be inextensional with plane sections remaining plane and to obey a bi-linear stress...
