A Theoretical Analysis For The Dynamic Axial Crushing Of

Apr 01, 1999 An approximate theoretical analysis is presented for the mean crushing forces generated during the dynamic axial loading of top-hat and double-hat sections. The theoretical predictions compare favourably with experimental results reported in a companion article on spot-welded mild steel sections and with the empirical equations and theoretical ...

Numerical Dynamic Axial Crushing Of Bi

Thin walled multi-cell columns are highly efficient in energy absorption under axial crushing loads. In this study, the dynamic axial crushing of bi-tubular metallic cylindrical tubes is numerically studied. Proposed Bi-tubular tubes are unique in the feature as the inner tube is conical in shape and outer tube is circular, along with ...
