The effect of model updating of crash box structures with trigger mechanisms towards the crashworthiness output of the structures

This paper would focus on the structure of aluminium alloy spot welded crash box with the trigger mechanism as the structure are widely studied for its crashworthiness as well as the location of the structure itself at the car chassis which are subjected to dynamic loading of the car. Aluminium allo...
