Subsequently, a new crushing band that is nearly parallel with the already existed crushing band is developed at a nominal strain of about 0.42, as shown in Fig. 5. For PA12 s with a relative density of 12.1%, the initial shear band occurs near the mid-height of the specimen whereas a new inclined crushing band appears near the …
The axial crushing behavior of the GHH tubes is investigated in terms of deformation modes, crushing forces and energy absorption. Theoretical solutions are also derived to predict the mean crushing forces (MCFs) of the GHH tubes. Two deformation modes have been identified, a locally layer-by-layer folding deformation (Mode-L) and a …
