Shrinkage-Constrained Functional Calibration for Complex Computer Models
Liam Myhill, Enrique Martinez, Sez Russcher
We propose a new Bayesian model calibration formalism as an alternative to the Kennedy O'Hagan (KOH) framework which we term integrated bias with full uncertainty (IBFU). In KOH, c…
Bayesian Model Calibration with Integrated Discrepancy: Addressing Inexact Dislocation Dynamics Models
Liam Myhill, Enrique Martinez Saez, Sez Russcher
In this work, a novel approach to Bayesian model calibration routines is developed which reinterprets the traditional definition of model discrepancy as defined by Kennedy and O'Ha…
Activation entropy helps explain anomalous flow stress temperature dependence in copper
Mohammadhossein Nahavandian, Liam Myhill, Enrique Martinez
Thermal activation of dislocations is critical for predicting the mechanical response of materials under common experimental conditions. According to transition state theory (TST),…
Data-Driven Modeling of Dislocation Mobility from Atomistics using Physics-Informed Machine Learning
Yifeng Tian, Soumendu Bagchi, Liam Myhill +5
Dislocation mobility, which dictates the response of dislocations to an applied stress, is a fundamental property of crystalline materials that governs the evolution of plastic def…
