Graduate School of
Science and Engineering

This laboratory is carrying out many fatigue tests under multiaxial loadings for various materials, such as heat and corrosion registrant alloys used for high temperature component, light weight alloys and super alloys used for aircraft, low melting alloys used for electronic devices, etc. Based on the obtained test results, deformation and fracture behaviors are evaluated. Observations of crack and microstructure, analyses and evaluations of results and numerical analyses are also carried out, and then evaluation of strength and development of design criteria for fatigue strength are studied. For the multiaxial fatigue test, since special test equipment is needed, almost all the machines are the originally designed and fabricated testing equipment. New testing machines are also developed. Thus, the students can study not only materials and strength of material, but also programing of test controlling and hydraulic control system. In this laboratory, most important thing is to enjoy the research work.
