Wei Cai

Wei Cai is a Professor of Mechanical Engineering and, by courtesy, of Materials Science and Engineering at Stanford University. His research focuses on predicting mechanical strength of materials through theory and simulations of defect microstructures across atomic, mesoscopic, and continuum scales. He develops new atomistic simulation methods for long time-scale processes, such as crystal growth and self-assembly. Additionally, he applies machine learning techniques to materials research and conducts modeling and experiments on metallurgical processes in metal 3D printing. His work also explores microstructure-property relationships in materials for stretchable electronics, including carbon nanotube networks and semiconducting elastomers.

Wei Cai is a Professor of Mechanical Engineering at Stanford University, specializing in Computational Materials Science, Dislocation, and Crystal Growth. His research focuses on understanding the behavior of dislocations in materials and their role in crystal growth and plasticity. He has conducted extensive simulations to study dislocation dynamics, including strain hardening, dislocation multiplication, and interactions with grain boundaries. His work also explores the mechanics of nanowires and the impact of dislocation core effects on mobility. Additionally, he investigates surface-controlled dislocation phenomena and the development of stretchable, self-healable semiconducting polymer films for flexible electronics.
