Mechanical Safety Design Laboratory

Nondestructive methods for Mechanical Safety

Masaru Ogawa: Associate Professor

This laboratory aims to improve safety and security in mechanical engineering. New nondestructive methods are invented and eveloped to predict remaining useful life of mechanical products. Three-dimensional welding residual stresses are estimated using X-ray diffraction. A nondestructive method to estimate inelastic strains using deformation has been proposed to evaluate the quality of the in turbine rotor blade.

Topics of research
  • Prediction of remaining useful life
  • Evaluation of residual stresses
  • 3D inelastic strain estimation
