Constrained Gaussian Random Fields with Continuous Linear Boundary Restrictions for Physics-informed Modeling of States
Yue Ma, Oksana A. Chkrebtii, Stephen R. Niezgoda
Boundary constraints in physical, environmental and engineering models restrict smooth states such as temperature to follow known physical laws at the edges of their spatio-tempora…
A Framework for the Optimal Selection for High-Throughput Data Collection Workflows by Autonomous Experimentation Systems
Rohan Casukhela, Sriram Vijayan, Joerg R. Jinschek +1
Autonomous experimentation systems have been used to greatly advance the integrated computational materials engineering (ICME) paradigm. This paper outlines a framework that enable…
Bayesian Inference for Polycrystalline Materials
James Matuk, Oksana Chkrebtii, Stephen Niezgoda
Polycrystalline materials, such as metals, are comprised of heterogeneously oriented crystals. Observed crystal orientations are modelled as a sample from an orientation distributi…
Investigating the origin of cube texture during static recrystallization of fcc metals : A full field crystal plasticity-phase field study
Supriyo Chakraborty, Chaitali S. Patil, Yunzhi Wang +1
The origin of cube recrystallization texture in medium to high stacking-fault energy fcc metals has been debated for almost 70 years. Despite numerous experimental and simulation s…
Analysis of Misorientation Relationships between Austenite Parents and Twins
Alexander F. Brust, Stephen R. Niezgoda, Victoria A. Yardley +1
The forward transformation from face centered cubic austenite to body centered cubic/tetragonal martensite in ferrous alloys can significantly in- fluence the microstructure and me…
Modeling the Thermal Stability of the Microstructure in Shocked Zr: Coupling between defect state and phase transformation
Stephen R. Niezgoda, Thaddeus Song En Low
Under high pressure, Zr undergoes a transformation from its ambient equilibrium hexagonal close packed phase to a simple hexagonal phase. Subsequent unloading to ambient co…
Symmetrized Bingham Distribution for Representing Texture: Parameter estimation with respect to crystal and sample symmetries
Stephen R. Niezgoda, Eric A. Magnuson, Jared Glover
The quaternion Bingham distribution has been used to model preferred crystallographic orientation, or crystallographic texture, in polycrystalline materials in the materials scienc…
Long-time behavior of the transition in shocked Zirconium: Interplay of nucleation and plastic deformation
Cristiano Nisoli, Honxiang Zong, Stephen R. Niezgoda +2
We study the thermally activated, slow conversion of the hysteretically retained phase into stable phase in recovered samples of shocked zirconium. The -phase decays in…
An integrated full-field model of concurrent plastic deformation and microstructure evolution: Application to 3D simulation of dynamic recrystallization in polycrystalline copper
Pengyang Zhao, Thaddeus Song En Low, Yunzhi Wang +1
Many time-dependent deformation processes at elevated temperatures produce significant concurrent microstructure changes that can alter the mechanical properties in a profound mann…
Isothermal Annealing of Shocked Zirconium: Stability of the Two-phase Microstructure
Thaddeus Song En Low, Donald W. Brown, Brian A. Welk +3
Under high pressure conditions, Zr undergoes a phase transformation from its ambient equilibrium hexagonal close packed phase to hexagonal phase. Upon returning to ambient…
