ABSTRACT:
A method of making an energy-absorbing structure in the form of a sheet having a pattern of alternating front and rear projections in front of and behind a median plane with each projection having an end face, a pitch region spaced from the end face, and a transition region therebetween including varying at least one parameter of the structure from the group consisting of local variation in sheet thickness in the pitch region, local variation in slope in the pitch region, geometry of the end face and geometry of the transition region, analyzing the energy absorption characteristics of the structure in response to the variation of the or each parameter, selecting the value of the or each parameter which gives a desired absorption characteristic and making a structure with the selected values of the or each parameter.
