Research Interest

Mark studies the mechanics of conventional and auxetic cellular solids under different loading, operating, and environmental conditions for biomechanical and space applications. The scientific objective is to investigate the multiscale deformation mechanisms responsible for the impact efficacy of elastomeric foams in single and repeated loading scenarios as a function of strain rate, temperature, and microcellular structure. Mark will investigate the performance of conventional polyurea elastomeric foams produced in the lab based on patented technology in mono and density-graded configurations in one research vector. Mark will submit the foam to static, impact, and dynamic loading to fully understand the macro and microscale deformation mechanisms and their interrelationship. In another research direction, Mark will convert polyurea foams (mono-density and density-graded) to an auxetic structure, benchmarking the performance to their conventional counterparts investigated in the companion research vector. Conformational changes will be emphasized after mechanical loading using terahertz-based characterization approaches.
