Hosoi Lab
Machine-translated · View original
A materials mechanics lab that investigates the strength and fracture of materials through experiments and analysis.
AboutAbout the lab
Investigating the strength of materials from the small-scale world
The Hosoi Lab conducts research to make structural materials and functional materials last longer in use.
The lab investigates the strength and fracture of materials, from the nanoscale to the visible scale, using both experiments and analysis.
It combines experiments using tools such as atomic force microscopes and high-speed cameras with computer-based analysis.
Key terms
- Fatigue crack
- A crack that gradually grows as a material is subjected to repeated loading
- CFRP (carbon fiber reinforced composite)
- A lightweight, strong material that combines carbon fibers and plastic
- Nanoporous structure
- A structure in which tiny, nanometer-sized pores are arranged in a regular pattern

ResearchResearch themes
To ensure that structural materials and functional materials can be used safely for a long time, the lab evaluates the strength and fracture of materials, from the nanoscale to the macroscale, through both experiments and analysis.
*Illustrative imageHealing of Fatigue Cracks in Metals
The lab studies techniques that close cracks caused by fatigue and restore strength by passing a high-density electric current through metals or applying heat treatment.
*Illustrative imageLong-Term Reliability Evaluation of CFRP
The lab examines fatigue damage in carbon fiber reinforced composites (CFRP) at the nanometer scale and builds models that predict when damage begins.
*Illustrative imageDevelopment of Bio-Inspired Functional Materials
Taking inspiration from biological structures such as seashells, the lab creates regularly arranged nanometer-sized pores (nanoporous structures) on aluminum surfaces to develop new materials that are lightweight and strong.
