Shibanuma Lab
Machine-translated · View original
A fracture mechanics lab that uses models to explain how and why things break.
AboutAbout the lab
Explaining fracture phenomena through theory, experiments, and computation.
The Shibanuma Lab studies fracture, the process by which materials and structures break.
Fracture is closely tied to the safety of buildings and machines, and predicting and controlling it is essential both for designing new materials and structures and for reducing risks to human life.
The lab combines theory, experiments, computation, and data science, aiming to establish new methods for explaining fracture phenomena.
Fracture mechanics is a discipline that spans a wide range of engineering fields, including mechanical engineering, materials science, naval architecture and ocean engineering, aerospace engineering, and civil engineering.
Key terms
- Fracture mechanics
- The field that uses mechanics to study how cracks in materials and structures form, grow, and lead to failure
- Fatigue
- A form of degradation in which repeated loading causes cracks to form in a material and gradually grow
- Finite element method (FEM)
- A method that divides a structure into small elements and uses a computer to calculate forces and deformation

ResearchResearch themes
The lab aims to gain a deeper understanding of fracture phenomena in order to improve and maintain the integrity of materials and structures. By combining theory, experiments, computation, and data science, it develops new models and experimental methods for explaining fracture.
*Illustrative imageNew models of fracture
The lab builds models that link factors across many scales, from entire structures down to the atomic level. It also places emphasis on developing computational methods that extend the finite element method (FEM), as well as on model verification and validation.
*Illustrative imageDiverse fracture phenomena
The lab studies fracture that occurs through different mechanisms, including fatigue, brittle fracture, ductile fracture, and creep. It aims to treat all of these within a single framework, using new models that share common elements.
*Illustrative imageNew experimental and observational methods
The lab develops new experimental and observational methods by combining imaging technology with numerical simulation. Its work includes in situ observation of fracture using high-speed cameras and other tools, as well as research on accurately determining material properties.
