A generalized calculation of the rate independent single crystal yield surface
Matthew Kasemer, Paul R. Dawson
In this paper, we discuss a method to calculate the topology of the rate independent single crystal yield surface for materials with arbitrary slip systems and arbitrary slip stren…
Orientation reconstruction of transformation titanium alloys via polarized light microscopy: methodology and assessment
Amit Singh, Mark Obstalecki, Darren C. Pagan +2
Emerging microstructural characterization methods have received increased attention owing to their promise of relatively inexpensive and rapid measurement of polycrystalline surfac…
The influence of substantial intragranular orientation gradients on the micromechanical response of heavily-worked material
Karthik Shankar, Meddelin Setiawan, Katherine S. Shanks +3
In this study, we employ high-energy X-ray characterization to examine the role of relatively large amounts of intragranular lattice misorientation -- present after many thermomech…
Establishing the relationship between generalized crystallographic texture and macroscopic yield surfaces using partial input convex neural networks
Lloyd van Wees, Karthik Shankar, Jan N. Fuhg +4
In this study, we present a methodology to predict the macroscopic yield surface of metals and metallic alloys with general crystallographic textures. In previous work, we have est…
Graph Neural Network Modeling of Grain-scale Anisotropic Elastic Behavior using Simulated and Measured Microscale Data
Darren C. Pagan, Calvin R. Pash, Austin R. Benson +1
Here we assess the applicability of graph neural networks (GNNs) for predicting the grain-scale elastic response of polycrystalline metallic alloys. Using GNN surrogate models, gra…
Machine-learning convex and texture-dependent macroscopic yield from crystal plasticity simulations
Jan N. Fuhg, Lloyd van Wees, Mark Obstalecki +3
The influence of the microstructure of a polycrystalline material on its macroscopic deformation response is still one of the major problems in materials engineering. For materials…
