Laboratory profile
We are working on the computer simulation of dynamics of lattice defects in metals. By simulating the dynamics of lattice defects on computers, microscopic mechanism of strengthening technique for metals and alloys are investigated. The influence of the microscopic mechanism on the macroscopic deformation behavior of the metals and alloys is modeled for enabling the quantitative evaluation of the strengthening by the technique as well. In addition, fracture mechanics analysis of cracks using dislocations and ductile fracture analysis are conducted.
