Orientation Optimization Based on Topological Derivatives in Cooperation with Multi-Material Topology Optimization Based on Extended Level Set Method
Masaki Noda, Kei Matsushima, Takayuki Yamada
This paper provides an orientation angle optimization method for the design of fiber-reinforced composite materials using topology optimization. The orientation angle optimization…
Level set-based shape optimization of deformable structures for manipulating sound propagation
Yuki Noguchi, Takayuki Yamada
In this paper, we propose a level set-based shape optimization method for acoustic wave propagation problems with a deformable structure. First, we propose a mathematical model for…
Topology optimization method with nonlinear diffusion
Tomoyuki Oka, Takayuki Yamada
This paper is concerned with topology optimization based on a level set method using (doubly) nonlinear diffusion equations. Topology optimization using the level set method is cal…
Level set-based multiscale topology optimization for a thermal cloak design problem using the homogenization method
Makoto Nakagawa, Yuki Noguchi, Kei Matsushima +1
Artificially designed composite materials consist of microstructures, that exhibit various thermal properties depending on their shapes, such as anisotropic thermal conductivity. O…
Two-Phase Topology Optimization for Metamaterials with Negative Poisson's Ratio
Daichi Akamatsu, Yuki Noguchi, Kei Matsushima +3
Although recent developments in 3D printing technology have made it possible to fabricate metamaterials with characteristic mechanical properties, it is not easy to fabricate compl…
Exceptional points in cylindrical elastic media with radiation loss
Kei Matsushima, Yuki Noguchi, Takayuki Yamada
Exceptional points (EPs) are singular points on a parameter space at which some eigenvalues (scattering poles) and their corresponding eigenmodes coalesce. This study shows the exi…
