Abstract For the protection of the human head by energy absorption structures, a soft mechanical response upon contact with the head is required to mitigate the effect of impact, while a hard mechanical response for highly efficient energy absorption

Since mechanical performances of the connecting part in the frame structure generally deteriorate, the mechanical performances may also deteriorate in the connecting part between the modules. If the design target is based on the existing parts, the b

A CAE-based process design method was developed to improve formability in hot stamping by controlling the temperature distribution during the forming step. Specifically, areas where deformation is not desired should be cooled to make them harder, and
