Welcome to CMMS at WSU


Researchers at Computational Mechanics and Materials Science Laboratory (CMMS) at Washington State University work on the thermo-mechanical behavior of solids, and address engineering and scientific phenomena spanning the length scale from nanometer to macrometer, and occurring under extreme loading and environmental conditions, with emphasis on damage, fracture and material instabilities.

On the small end of the length scale spectrum, nanometer to micrometer, work at CMMS includes understanding the physical characteristics and mechanical performance of metals and composites with emphasize on nano-laminate metallic structures, composite nano-wires, thin films and nano-particulate composites, for use in micromechanical systems, microelectronics, and medical devices.

On the large end of the length scale spectrum, micrometer to macrometer, researchers at CMMS investigate the behavior of metals and geological materials under extreme conditions, such as shockwaves, metal forming and high speed machining, superplastic forming, as well as earthquake and mechanics of  soil. They develop multiscale models that are based on first principles, and link scales by passing relevant information from one scale to another. They have made significant advancements in key theoretical and computational areas including multi-scale dislocation dynamics plasticity, dislocation theory, 3D-dislocation dynamics, molecular dynamics, crystal plasticity, and gradient theories.

Work at CMMS has been funded by a number of agencies, including the US National Science foundation, the Office of Basic Energy Science at the US Department of Energy, the US Army Research Office, Lawrence Livermore National Laboratory, Los Alamos National Laboratory, Pacific Northwest National Laboratory, ALCOA, the US National Institute of Standard and Technology, Sandia National Laboratory, and the Washington Technology Center.
