The lab studies optimal design, using computation to derive the best possible shape.
AboutAbout the lab
Using computation to create shapes that bring out the strength of materials.
The Structural Materials and Strength Lab conducts research on topology optimization, which uses computation to derive the best possible shape for structures and machines.
The lab studies design methods that take advantage of material properties across a range of fields, including mechanics, fluid dynamics, thermodynamics, and electrochemistry.
It works on a wide range of subjects, including rubber, metals, carbon fiber reinforced plastics, and all-solid-state batteries.
The lab belongs to the Department of Micro Engineering, Graduate School of Engineering, and students from the Department of Physical Science and Engineering are also assigned to it.
Key terms
- Topology optimization
- A method that uses computation to find the best shape of a structure, including where to place material and where to make holes
- All-solid-state battery
- A battery that uses a solid rather than a liquid as its electrolyte. It is expected to be a safe, high-performance next-generation battery
- Anisotropic material
- A material, such as carbon fiber reinforced plastic, whose properties such as strength differ depending on direction

ResearchResearch themes
The lab studies design methods that use computational mechanics and topology optimization to derive structural shapes that bring out the full potential of material properties. It tackles problems in a wide range of fields, including mechanics, fluids, heat, and electrochemistry.
*Illustrative imageOptimal Shapes That Exploit Material Nonlinearity
Many materials show nonlinear properties such as ductility, plasticity, and damage, but conventional optimal design has treated materials as simple elastic bodies. By combining the theory of mechanics of materials with topology optimization, the lab derives shapes that make use of material characteristics.
*Illustrative imageSimultaneously Optimizing Fiber Orientation and Shape
Carbon fiber reinforced plastics are very strong along the fiber direction but weak in the perpendicular direction. To bring out the potential of such anisotropic materials, the lab works on research that simultaneously optimizes the shape of a structure and the orientation of the material.
*Illustrative imageOptimal Design That Exploits Contact and Friction
Structural problems involving contact and friction contain strong nonlinearity and discontinuities, which makes stable and accurate design difficult. The lab aims for a new design theory that rigorously formulates contact and friction and actively uses them as design degrees of freedom.
*Illustrative imageOptimizing the Shape of Fluid Machinery
Fluid machinery such as pumps and turbines is required to have high efficiency and reduced vibration and noise. The lab predicts internal flows involving rotation through numerical simulation and studies new design methods that combine this with topology optimization.
