Mesoscale Description of Interface-Mediated Plasticity
Jinxin Yu, Alfonso H. W. Ngan, David J. Srolovitz +1
Dislocation-interface interactions dictate the mechanical properties of polycrystalline materials through dislocation absorption, emission and reflection and interface sliding. We…
Simulations of grain growth in tungsten armor materials under ARC plasma edge operation conditions using an integrated plasma-edge/materials model
Jinxin Yu, Nithin Mathew, Sophie Blondel +5
An integrated model of grain growth deuterium-exposed tungsten polycrystals, consisting of a two-dimensional vertex dynamics model fitted to atomistic data, has been developed to a…
Application of Rigorous Interface Boundary Conditions in Mesoscale Plasticity Simulations
Jinxin Yu, Alfonso H. W. Ngan, David J. Srolovitz +1
The interactions between dislocations and interface/grain boundaries, including dislocation absorption, transmission, and reflection, have garnered significant attention from the r…
A Mesoscale Model for Interface-Mediated Plasticity: Investigation of Ductile and Brittle Fracture
Jinxin Yu, Alfonso H. W. Ngan, David J. Srolovitzb +1
The presence of interfaces and grain boundaries significantly impacts the mechanical properties of materials, particularly when dealing with micro- or nano-scale samples. Distinct…
Irradiation-Driven Recrystallization in Fusion-Grade Tungsten: A Mesoscale, Microstructure-Aware Model
Jinxin Yu, Sicong He, Giacomo Po +3
Tungsten (W) is the leading candidate material for plasma-facing components in fusion reactors, yet its upper operational temperature is limited by premature grain growth and recry…
From Buffers to Registers: Unlocking Fine-Grained FlashAttention with Hybrid-Bonded 3D NPU Co-Design
Jinxin Yu, Yudong Pan, Mengdi Wang +4
Transformer-based models dominate modern AI workloads but exacerbate memory bottlenecks due to their quadratic attention complexity and ever-growing model sizes. Existing accelerat…
