William Curtin
William A. Curtin is an American materials scientist who is Elisha Benjamin Andrews Professor at Brown University in Providence, Rhode Island.[2] From 2011 to 2022, he was director of the Institute of Mechanical Engineering at École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland. He received a Guggenheim Fellowship in 2005.[1] His research interests span a wide range of topics in materials science and theoretical physics, including the mechanics of materials, multiscale modeling, and the properties of metal alloys and composites.[2] He is the author of several high-impact publications in the field of materials science.[3] He was editor-in-chief of Modelling and Simulation in Materials Science and Engineering for more than ten years until 2016.[4] Curtin proposed a new model for the Portevin–Le Chatelier effect (PLC effect), which is based on the "single-atomic-hop motion of solutes from the compression to the tension side of a dislocation core." This model provides a predictive framework for understanding dynamic strain ageing (DSA) in these alloys, offering new insights into the microscopic interactions that lead to macroscopic material behaviors.[5] References
