SplineNet: An Isogeometric Deep Learning Method for Complex Shells
Shizhou Luo, Xiaodong Wei
We present a novel isogeometric deep learning method, termed SplineNet, for the seamless design and analysis of shell structures with complex geometries. The proposed approach is b…
eCNNTO: A Highly Generalizable ConvNet for Accelerating Topology Optimization
Shengbiao Lu, Xiaodong Wei
This work proposes an element-based Convolutional Neural Network (CNN) to accelerate density-based Topology Optimization (TO), termed eCNNTO. TO generally undergoes a large number…
Weighted Quadrature on Unstructured Splines
Ji Sheng, Xiaodong Wei, Falai Chen
This work presents a weighted quadrature (WQ) method to fast assemble Galerkin matrices based on unstructured spline surfaces. The method is developed upon a particular variant of…
PolyCrysDiff: Controllable Generation of Three-Dimensional Computable Polycrystalline Material Structures
Chi Chen, Tianle Jiang, Xiaodong Wei +1
The three-dimensional (3D) microstructures of polycrystalline materials exert a critical influence on their mechanical and physical properties. Realistic, controllable construction…
