Development of a Controlled Fracture Device for Disaster Rescue
We are developing a controlled fracture technique that uses a small amount of nitromethane to create a fracture plane at a designated location in reinforced concrete. The aim is to facilitate the rapid establishment of rescue access routes at disaster sites.
Dissimilar Materials Joining
We are developing new methods for joining dissimilar materials, including explosive welding and vaporizing foil actuator welding (VFAW), which utilizes the electrical explosion of a metal foil.
Explosive Forming
We investigate forming technologies in which shock waves deform thin metal sheets at high velocity and transfer the shape of a die to the workpiece. In addition to forming complex geometries, we study the transfer of micro- and nanoscale surface structures.
Shock Synthesis
We investigate techniques for synthesizing new materials by utilizing the high-temperature and high-pressure states generated by detonation, followed by rapid quenching. Our research focuses on the synthesis of high-pressure phases and functional materials, including diamond.
