Welcome to Miyashita-Otsuka Lab!

This page introduces the activities of Nagaoka University of Technology’s Mechanical Strength · Joining Engineering Laboratory (Miyashita Lab) and System Safety System Structural Safety Assessment Laboratory (Muto · Otsuka Lab.). While exploiting material dynamics and fracture mechanics, we studied fracture mechanism for maintaining the soundness of mechanical structure, development of evaluation method, process evaluation and material design for high strength and long life It is.
