Takahashi Lab
Machine-translated · View original
A lab that simulates the strength of materials from the motion of microscopic defects inside them.
AboutAbout the lab
Reading material strength from the motion of microscopic defects
The Takahashi Lab uses computer simulation to study problems of material strength caused by dislocations and other defects inside materials.
Based on the concept of multiscale modeling, the lab builds mathematical models of dislocation dynamics.
These simulations can reveal how the microscopic properties of dislocations and their interactions with other defects affect the mechanical properties of a material as a whole.
By solving materials problems across wide spatial and temporal scales, the lab aims at high-accuracy materials design based on controlling the motion of microscopic defects.
Key terms
- Multiscale modeling
- A modeling approach that links phenomena of different sizes, from micro to macro, to investigate the properties of a material
- Dislocation
- A type of microscopic defect in a material. The motion of defects determines the macroscopic deformation behavior of the material
ResearchResearch themes
This lab turns the motion of microscopic defects into mathematical models and investigates the deformation and strength of materials through simulation. By understanding deformation behavior in detail from the micro to the macro scale, it aims to realize high-accuracy materials design.
