Research Interests
Materials, bioinspiration, micro-architecture
Nature produces materials with highly attractive sets of properties which can inspire new strategies for stronger, tougher, lighter, smarter and more sustainable engineering materials. Professor Francois Barthelat's research group (1) characterizes the structure, mechanics and multi-functionalities of natural materials and (2) designs, fabricates and tests novel high-performance engineering materials and systems inspired by nature. Their current models include mollusk shells, bone, teeth, collagen, fish scales and osteoderms. Their daily activities involve micromechanics, fracture mechanics, modeling of nonlinear and dissipative processes in materials, contact and impact mechanics, finite elements modeling, discrete element modeling, topology and geometrical optimization, laser engraving, 3D printing, experimental mechanics and also a bit of biology.
Societal Impact
We develop lighter and stronger materials that can ultimately results in large savings in transportation. We also develop new bone graft materials that are strong yet biocompatible, biodegradable and with little change of infections. One of our recent projects involved the development of protective industrial gloves inspired from fish-scales, to minimize hand injuries in work environments. Finally, our design approach duplicates nature’s: make more with less, develop high information, high performance materials based on modest but sustainable ingredients.
