Where l eff is the effective crushing distance and is set as 190 mm. The CFE is defined as: (5) CFE = MCF PCF. The energy dissipated over the crushing region is calculated as follows. The SEA is the ratio between EA and the mass. (6) EA = ∫ 0 l eff Fd s. 4. Simulation results. This section illustrates the crushing behaviors of HMSA and …

In the second stage, the crushing mechanism continues and the transverse section geometry suffers significant changes (point 3), developing larger deformed zones at the singular points. In the final stage, the load increases gradually as the amount of collapse hinges increases (point 4) and the inner walls of the sections make contact (point 5 ...

During crushing, an open section composite structure may exhibit a number of failure modes including intralaminar shear, axial cracking and transverse ply failure which produce a splaying or petalling mode of failure [9]. To adequately represent these failure modes a detailed numerical analysis methodology capable of capturing these failure ...

The crushing behavior of circle tube under bending has also been studied analytically and experimentally. Elchalakani conducted a plastic mechanism analysis for thin-walled hollow section tubes deforming in a diamond or multi-lobe collapse mode under large deformation pure bending [16]. ...
