Deformation Control Lab
Machine-translated · View original
The lab determines shapes through optimal design, from composite materials to stents.

AboutAbout the lab
Applying the fundamentals of mechanical engineering to a wide range of industries
The Deformation Control Lab aims to apply the fundamentals of mechanical engineering, namely mechanics of materials, vibration engineering, optimal design, and thermo-fluid dynamics, to a wide range of industrial fields.
The lab works on the optimal design of new functional composite materials and of next-generation aerospace equipment using physics-based AI models.
Its research themes also include vibration control of smart composites and the development of new manufacturing methods for composites.
The lab also conducts biomechanics research, including stents used to treat arteriosclerosis, motion analysis of the knee joint, and the development of artificial joints.
Key terms
- Optimal design
- Using calculation to find the best shape or combination of materials within given conditions
- Anisotropy
- Having properties that change depending on direction. It is seen in materials such as composites, whose strength varies with the direction of the fibers
- Stent
- A medical tube made of metal mesh that is placed in a narrowed part of a blood vessel or similar to widen it

ResearchResearch themes
The lab aims to apply the fundamentals of mechanical engineering, namely mechanics of materials, vibration engineering, optimal design, and thermo-fluid dynamics, to a wide range of industrial fields. Each faculty member covers a broad range of themes, from the optimal design and new manufacturing methods of composite materials to biomechanics such as stents and the knee joint.
*Illustrative imageDevelopment of optimization techniques
Optimization and optimal design are technologies closely tied to every field of engineering and industry. While studying their application to mechanical products and composite structures, the lab also develops genetic algorithms, new methods inspired by the biological world such as PSO and ACO, and sequential approximate optimization methods.
*Illustrative imageMechanical analysis of composite structures
Carbon fiber reinforced composites (CFRP) are made by laminating anisotropic materials, which makes their mechanical analysis difficult. The lab develops analysis software and models that take material anisotropy into account, and works on creating analysis and optimization methods for composites with local anisotropy or curved reinforcing fibers.
*Illustrative imageMaking composites by electrodeposition resin impregnation
This is a method of making CFRP laminates by using electrodeposition technology to impregnate carbon fiber preforms with resin. Because the resin is deposited electrochemically, voids are unlikely to form, and because the resin does not flow, the shape of curved fibers is not disturbed.
*Illustrative imageDesign of custom-made stents
Off-the-shelf stents are standardized and cannot take individual differences in the state of stenosis into account. Making full use of finite element analysis and topology optimization, the lab is building a system that designs a stent tailored to each individual and goes as far as producing it with a 3D printer.
