Impedance-Guided Programmable Transmission of Localized Deformation in Modular Soft Metamaterials
Weiyun Xu, Daewon Hong, Zhi Zhao +2
Soft metamaterials provide a promising platform for robotics, biomedical devices, and flexible electronics. The localized mechanical responses by nonuniform excitation are ubiquito…
Boosting lattice polarization Mixing the perspectives of geometry optimization and cell-augmentation
Pegah Azizi, Rahul Dev Kundu, Xiaojia Shelly Zhang +1
Topologically polarized mechanical metamaterials enjoy a special built-in asymmetry that manifests as a preferred localization of edge states on selected edges. While this property…
Lattice Materials with Topological States Optimized On-Demand
Pegah Azizi, Rahul Dev Kundu, Weichen Li +3
Topological states of matter, first discovered in quantum systems, have opened new avenues for wave manipulation beyond the quantum realm. In elastic media, realizing these topolog…
Multimaterial topology optimization for finite strain elastoplasticity: theory, methods, and applications
Yingqi Jia, Xiaojia Shelly Zhang
Plasticity is inherent to many engineering materials such as metals. While it can degrade the load-carrying capacity of structures via material yielding, it can also protect struct…
Momentum-based Accelerated Mirror Descent Stochastic Approximation for Robust Topology Optimization under Stochastic Loads
Weichen Li, Xiaojia Shelly Zhang
Robust topology optimization (RTO) improves the robustness of designs with respect to random sources in real-world structures, yet an accurate sensitivity analysis requires the sol…
Stochastic Sampling for Structural Topology Optimization with Many Load Cases: Density-Based and Ground Structure Approaches
Xiaojia Zhang, Eric de Sturler, Glaucio H. Paulino
We propose an efficient probabilistic method to solve a deterministic problem -- we present a randomized optimization approach that drastically reduces the enormous computational c…
