Univariate Conditional Variational Autoencoder for Morphogenic Patterns Design in Frontal Polymerization-Based Manufacturing

Autor: Liu, Qibang, Cai, Pengfei, Abueidda, Diab, Vyas, Sagar, Koric, Seid, Gomez-Bombarelli, Rafael, Geubelle, Philippe

Under some initial and boundary conditions, the rapid reaction-thermal diffusion process taking place during frontal polymerization (FP) destabilizes the planar mode of front propagation, leading to spatially varying, complex hierarchical patterns in

Nonlinear Inverse Design of Mechanical Multi-Material Metamaterials Enabled by Video Denoising Diffusion and Structure Identifier

Autor: Park, Jaewan, Kushwaha, Shashank, He, Junyan, Koric, Seid, Liu, Qibang, Jasiuk, Iwona, Abueidda, Diab

Metamaterials, synthetic materials with customized properties, have emerged as a promising field due to advancements in additive manufacturing. These materials derive unique mechanical properties from their internal lattice structures, which are ofte

Adaptive coupling peridynamic least-square minimization with finite element method for fracture analysis

Autor: Liu, Qibang, Xin, X. J., Ma, Jeff

This study presents an adaptive coupling peridynamic least-square minimization with the finite element method (PDLSM-FEM) for fracture analysis. The presented method utilizes the PDLSM modeling discontinuities while maximizing the FEM region for comp

An extended ordinary state-based peridynamics for non-spherical horizons

Autor: Liu, Qibang, Chen, Muhao, Skelton, Robert E.

This work presents an extended ordinary state-based peridynamics (XOSBPD) model for the non-spherical horizons. Based on the OSBPD, we derive the XOSBPD by introducing the Lagrange multipliers to guarantee the non-local dilatation and non-local strai
