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…
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…
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…
