Presentation Title Finite Element Implementation of a Dislocation Thermo-mechanics Model: Application to Study Dislocation Structure Evolution during Laser Scanning
Author(s) Gabriel Dante Lima Chaves, Manas Upadhyay
On-Site Speaker (Planned) Manas Upadhyay
Abstract Scope Recently, a thermo-mechanical model of field dislocations (T-FDM), was proposed by Upadhyay, JMPS 145 (2020) 104150. The motivation behind the development of this model was two-fold: (i) to study the dynamics of dislocations under transient heterogeneous temperature fields such as those occurring during metal additive manufacturing, welding, quenching, and other thermomechanical processes, and (ii) to capture the temperature changes induced via dislocation dynamics. In the present study, the partial differential equations (PDEs) of the T-FDM model are numerically solved using the finite element (FE) method. The model is implemented in FEniCS, which is an open-source platform built to solve PDEs via the FE method. In this talk, the governing equations of the T-FDM model will be presented. Their numerical implementation will be followed by some illustrative examples. Specifically, dislocation patterning induced during laser scanning of a metal microstructure, similar to that occurring during additive manufacturing, will be shown.
