Table 1. Values for calculation of impact forces using Equation 1, for 36 kg Homalocephale colathoceros and 488 kg Pachycephalosaurus wyomingensis, at closing speeds of 6.7 and 3 m/s for each. In Pachycephalosaurus the highest stress is for a focused point impact, and the alternate high stress is for the software's point force application. Peak stresses diminish indirect proportion with diminishing forces.
