New LNG storage system and advanced materials

The contribution to natural gas in our energy sources is increasing. In our laboratory, the natural gas policy that should be taken in the future and the requirements for new LNG storage and transport systems and materials for cryogenic use based on the policy are examined. We will colaborate with various players in the energy gas field (government, trading companies, Talk with owners, engineering, fabricators, and material manufacturers) to propose a combination of design and materials that are economically rational.

Establish safety of soft joints its actual use

In the fatal brittle failure of large structures, the welded part is important for preventing the accident. Aboce all, it is most important not to leave cracks or defects in the weld. Welds are complicated, such as the difference in strength from the base metal due to the essentially different metal structure. However, when this heterogeneity is positively incorporated, especially when a soft material is disposed in the welded metal portion, various advantages are considered to be produced, but it is not actively utilized at the moment. Our laboratory aims to improve economic rationality by considering fracture characteristics and active utilization of heterogeneous welds.

Deeper understanding of steel fracture process and prediction technology

Steel materials are the most abundant metal resources on earth and will continue to be the most important structural materials in the future. Human being has experienced many massive failure accident and has a history of struggling to prevent it. However, due to the complexity of the metal structure, a complete understanding of the destruction phenomenon has not been reached. We will establish an innovative fracture mechanics models that take into account new microscopic perspectives and obtain development guidelines for next-generation advanced materials.

Message
The safety of energy facilities and equipment is extremely important for sustaining the cultural lives of people around the world. It is a problem that must be solved. Let's consider future prospects from the perspective of materials.
