A baseline test consisting of a test platform with a V-shape body exposed to the charge was executed, recording the imparted impulse and the deformation of the test item. A collapsible structure is added to the test platform and tested (two tests). By the law of conservation of momentum, similar peak imparted impulse values were obtained. However, the average imparted impulse reduced by between 16 % to 18% by adding this collapsible element in the load path. The average impulse is the total momentum transferred after the response of the damping system is filtered into the measurement system. The results are analysed with ANSYS AUTODYN and support the measured effects of the introduction of the mitigation measure.Defence Science Journal, 2013, 63(3), pp.262-270, DOI:http://dx.doi.org/10.14429/dsj.63.2308 ER -
