Abstract This work presents a revision of the structural similarity technique developed for experimental modeling marine structures subjected to collision, grounding or similar catastrophic events via miniature models with drastic scale reduction. involved basically inclusion combined collapse modes predict mechanical behavior members and redefinition flow stress range. The revised was validate...

In order to reduce both the weight of vehicles and the damage of occupants in a crash event simultaneously, it is necessary to perform a multi-objective optimization of the automotive energy absorbing components. In this paper, axial impact crushing behavior of the aluminum foam-filled thin-walled tubes are studied by the finite element method using commercial software ABAQUS. Comparison of the...

In this paper, numerical simulation of FRP composite cylinder tubes progressive crushing processes is conducted using LS-Dyna. Details on the numerical modeling strategy are given and discussed. It is found that triggers introduced in the numerical simulation can effectively model the bevel trigger at the end of the tubular specimens. It is also found that two-layer finite element model based o...
