Continuous approximation of material distribution for topology optimization
Kazumi Matsui,Kenjiro Terada +1 more
TL;DR: In this paper, a checkboard-free topology optimization method without introducing any additional constraint parameter is proposed, which is called the method of continuous approximation of material distribution (CAMD) to emphasize the continuity imposed on the material field.
Journal ArticleDOI
Finite element modeling of multi-pass welding and shaped metal deposition processes
Michele Chiumenti,Miguel Cervera,Alessandro Salmi,Carlos Agelet de Saracibar,Narges Dialami,Kazumi Matsui +5 more
TL;DR: In this article, the authors describe the formulation adopted for the numerical simulation of the shaped metal deposition process (SMD) and the experimental work carried out at ITP Industry to calibrate and validate the proposed model.
Journal ArticleDOI
Two-scale finite element analysis of heterogeneous solids with periodic microstructures
TL;DR: This work makes a feasibility study and introduces a parallel algorithm to achieve the computational efficiency of a two-scale analysis method for nonlinear heterogeneous solids with periodic microstructures.
Journal ArticleDOI
Structural topology optimization of vibrating structures with specified eigenfrequencies and eigenmode shapes
Yasunori Maeda,Shinji Nishiwaki,Kazuhiro Izui,Masataka Yoshimura,Kazumi Matsui,Kenjiro Terada +5 more
TL;DR: In this article, a new topology optimization method for designing vibrating structures that targets desired eigenfrequencies and eigenmode shapes is proposed, which is applicable to the design of mechanical resonators and actuators.
Journal ArticleDOI
Two-scale kinematics and linearization for simultaneous two-scale analysis of periodic heterogeneous solids at finite strain
TL;DR: In this paper, the authors introduce the notion of two-scale kinematics and the procedure of twoscale linearization, which are indispensable to the simultaneous twoscale analysis of periodic heterogeneous solids at finite strain.
