Meeting 2027 TMS Annual Meeting & Exhibition
Symposium Verification, Calibration, and Validation Approaches for Mechanical Modeling of Metals
Presentation Title Quantitative approaches to incorporating in situ and postmortem stress fields from HR-EBSD into material models
Author(s) Tim Ruggles, William Gilliland, Thomas Bennett
On-Site Speaker (Planned) Tim Ruggles
Abstract Scope Mesoscale modelling is a powerful tool for predicting material behavior, but these models are often calibrated using macroscale data or informed from lower length scale ab initio simulations. Full field stress and strain data at the length scale of the microstructure of a material can be a powerful tool for calibrating and developing these models. This presentation will explore high resolution electron backscatter diffraction (HR-EBSD) as a means of mapping stresses and dislocation content in situ or postmortem providing data-rich information on mesoscale plastic and failure behavior. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525.
