A Statistical Perspective for Predicting the Strength of Metals: Revisiting the Hall-Petch Relationship using Machine Learning
Yejun Gu, Christopher D. Stiles, Jaafar A. El-Awady
The mechanical properties of a material are intimately related to its microstructure. This is particularly important for predicting mechanical behavior of polycrystalline metals, w…
AlloyVAE: A generative model for complex probabilistic field-to-field relationships in alloys
Ningyu Yan, Zhuocheng Xie, Kai Guo +3
The inherent compositional heterogeneity of multi-principal element alloys (MPEAs) gives rise to complex, spatially varying mechanical fields that cannot be uniquely determined fro…
Continuum Model and Numerical Method for Dislocation Structure and Energy of Grain Boundaries
Xiaoxue Qin, Yejun Gu, Luchan Zhang +1
We present a continuum model to determine the dislocation structure and energy of low angle grain boundaries in three dimensions. The equilibrium dislocation structure is obtained…
A Continuum Model for Dislocation Climb
Chutian Huang, Shuyang Dai, Xiaohua Niu +4
Dislocation climb plays an important role in understanding plastic deformation of metallic materials at high temperature. In this paper, we present a continuum formulation for disl…
Quantifying the effect of hydrogen on dislocation dynamics: A three-dimensional discrete dislocation dynamics framework
Yejun Gu, Jaafar A. El-Awady
We present a new framework to quantify the effect of hydrogen on dislocations using large scale three-dimensional (3D) discrete dislocation dynamics (DDD) simulations. In this mode…
RoCo Challenge at AAAI 2026: Benchmarking Robotic Collaborative Manipulation for Assembly Towards Industrial Automation
Haichao Liu, Yuheng Zhou, Zhenyu Wu +14
Embodied Artificial Intelligence (EAI) is rapidly developing, gradually subverting previous autonomous systems' paradigms from isolated perception to integrated, continuous action.…
