While textbooks define Solid Mechanics as the study of the motion, deformation, or fracture of solid materials to external and internal forces -- the breadth of this field is enormous. Solid Mechanics has implications for manufacturing, biomedicine, and much more.
Faculty members in the Solid Mechanics area study fundamentals of continuum mechanics, advance concepts in the field of micromechanics, advance numerical methods such as finite element and phase field approaches, and connect CAD to stress analysis. They work with analytical, numerical and experimental approaches.
In the application of Solid Mechanics faculty members seek to advance the reliability of microelectronic devices, the energy storage in batteries, the behavior of soft and hard tissue, the manufacturing of powder based products, and shape-changing structures.
