Mechanics of Composite Materials

This project involves the study of the mechanics of composites, including physical testing for strength, creep, and fatigue, computer modeling using FEM analyses, and Monte Carlo statistical simulations. We have studied the effect of plasma surface treatments on torsional fatigue, and are currently studying the use of resistance measurements to monitor fatigue damage in carbon/epoxy strands.
