A Method for the Derivation of Coefficients for the Constant Stiffness Force-Crush Model from Full-Engagement Front-to-Rigid Barrier Collision Tests Using Unequally Spaced Crush Profiles

Quantification of the planar residual damage profile present to a vehicle involved in a collision in conjunction with the appropriate force-crush model is a well-accepted method for estimating the energy absorbed by the vehicle structure and the barrier equivalent velocity (BEV) associated with the same. One such force-crush model, representing the first such model developed and perhaps the most commonly utilized, is that which assumes a linear relationship between the crush present to vehicle and the BEV. The model also assumes a linear relationship between the force applied per unit width of direct damage and the crush present. The historical development of this model, the assumptions behind it, and its normative implementation have been exposited upon in detail elsewhere. The aim of the present paper was to derive the equations of mathematical physics that allow for the quantification of the parameters for the constant stiffness force-crush model based on controlled front-to-rigid barrier full-engagement collision tests.
