Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Review of Junctions in FCC Metals" By Vignesh Vivekanandan Purdue MSE Ph.D. Preliminary Exam Advisor: Professor Anter El-Azab ABSTRACT Junctions are known to be responsible for the hardening behavior observed during plastic deformation in crystalline materials. In this review paper, the different types of junctions and their contribution to hardening is discussed. First, the junction formation process is explained based on linear elastic theories available in literature. Then their short comings and the need for DDD (Discrete dislocation dynamics) simulations is emphasized. Following that, different algorithms used to model junctions in DDD and the ways to characterize the junction formation process in DDD are summarized. Based on the characterization, the right way to incorporate the information in continuum models is explored. Date: Monday, November 26, 2018 Time: 10:30 A.M. Place: ARMS 1109
