She is an instructor in the introductory engineering courses as well. The BSEN program at MacEwan has grown from forty students since in started almost fifteen years ago, to the current 216 students. The majority of the students in the program transfer to second year engineering at the University of Alberta.

The circumstances in which we mechanically test and critically assess human calvaria tissue would find relevance under conditions encompassing real-world head impacts. These conditions include, among other variables, impact velocities, and strain rates. Compared to quasi-static loading on calvaria, there is less reporting on the impact loading of the calvaria and consequently, there are relatively fewer mechanical properties on calvaria at relevant impact loading rates available in the literature. The purpose of this work was to report on the mechanical response of 23 human calvaria specimens subjected to dynamic 4-point bending impacts. Impacts were performed using a custom-built 4-point impact apparatus at impact velocities of 0.86 to 0.89 m/s resulting in surface strain rates of 2-3/s - representative of strain rates observed in vehicle collisions and blunt impacts. The study revealed comparable effective bending moduli (11-15 GPa) to the limited work reported on the impact mechanics of calvaria in the literature, however, fracture bending stress (10-47 MPa) was relatively less. As expected, surface fracture strains (0.21-0.25%) were less compared to studies that performed quasi-static bending. Moreover, the study revealed no significant differences in mechanical response between male and female calvaria. The findings presented in this work are relevant to many areas including validating surrogate skull fracture models in silico or laboratory during impact and optimizing protective devices used by civilians to reduce the risk of a serious head injury.
