Fundamental areas of research and education are the mathematical modelings of various phenomena involved in the joining and the welding and their application to industrial problems through the information technology. Also, the influences of residual stress and various forms of defects on the performance of the welded joints or the joints between dissimilar materials are investigated.

In our laboratory, we apply the following two axes to structures’ design, construction, and maintenance process. The first is the “through-process,” which is the time axis that covers the life cycle of a structure from design, welding, joining, and other fabrication and construction processes, through testing and service to repair, reinforcement, and maintenance. The other is “trans-scale,” a spatial axis that spans from micro to macro, from the microstructure of materials to welding and joining components and the structure.
Education and research are conducted to evaluate the performance and reliability of various structures at each of these stages and scales. In particular, we are developing detailed and reasonable evaluation methods for the effects of thermal processing, as represented by residual stress and deformation, on the performance of welded/joined components and structures, considering both microscopic and macroscopic perspectives. We aim to establish an academic foundation that can contribute to the design of reliable structures by advancing structuring processes using welding and joining.
