A lab that explains how materials fracture, from the microscopic to the macroscopic scale.
AboutAbout the lab
Bridging the microscopic and the macroscopic to explain fracture.
The lab studies the mechanisms by which materials fracture, as well as the reliability of materials.
When a material is subjected to mechanical loads or environmental stress, deformation and cracks form in its fine internal microstructure, eventually leading to visible fracture.
Combining experimental observations with simulations that faithfully reproduce them, the lab investigates fracture from the mechanisms by which it begins to how the material fails as a whole.
The lab also aims to analyze the large volumes of data obtained from simulations to gain insights useful for materials design.
Key terms
- Fracture mechanics
- The field that uses the principles of mechanics to treat how cracks propagate within a material and lead to failure
- Nondestructive evaluation
- Methods for examining flaws and cracks inside materials or components without destroying them
- Data-driven science
- An approach to research that analyzes large amounts of data to find laws or clues for design

ResearchResearch themes
Combining experiments, simulation, and data science, the lab conducts end-to-end research, from elucidating the mechanisms of fine-scale damage inside materials to predicting how they fail as a whole. It aims to contribute to building a safe and secure social infrastructure.
*Illustrative imageObservation through Fracture Mechanics and Nondestructive Evaluation
Through experiments using fracture mechanics and nondestructive evaluation, the lab observes how deformation and cracks form in a material's internal microstructure when it is subjected to mechanical loads or environmental stress.
*Illustrative imageSimulations That Reproduce Fracture
The lab builds numerical simulations that faithfully reproduce the deformation and fracture observed in experiments, establishing a foundation for research that combines simulation with experiments.
*Illustrative imageData Science for Clues to Materials Design
The lab applies data-driven science to the large volumes of data obtained from simulations on the links among microstructure, microscopic fracture, and properties, and explores design strategies that optimize the properties of the material as a whole.
