Informationen zu Prof. Sakane und Prof. Itoh

Gastaufenthalt von Prof. Sakane, Prof. Itoh und Mr. Morishita (PhD) von der Ritsumeikan Universität in Japan am Institut für Werkstofftechnik vom 14.9. – 17.9.14

Seit dem Auslandsaufenthalt von Frau Ackermann (Teilprojekt B4) im letzten Jahr besteht zwischen dem Institut für Werkstofftechnik und den Professoren Sakane und Itoh von der Ritsumeikan Universität in Japan ein wissenschaftlicher Kontakt. Prof. Sakane war im letzten Jahr bereits für drei Tage zu Gast in Freiberg. Die wissenschaftlichen Diskussionen fanden Eingang in ein Manuskript, dass im Feb. 2014 bei International Journal of Fatigue veröffentlicht wurde (http://authors.elsevier.com/sd/article/S0142112314000565).

Some additional information about the guests

Prof. Dr. Masao Sakane
Ritsumeikan University
Faculty of Science & Engineering
Department of Mechanical Engineering
Chair: Reliability evaluation method for use with high-temperature materials and electronic device materials

Prof. Sakane is a world wide respected scientist in the field of fatigue and creep fatigue under multiaxial loading for more than 30 years. His research focuses on the development of a damage evaluation method and a strength evaluation method with regard to the multiaxial loading status of a wide range of high-temperature materials heat-resistant steel used in e.g. electric generation boilers and single-crystal superalloys that are used in aircraft and gas turbine blades for electric generation. Prof. Sakanes laboratory investigates fatigue behavior and also fatigue creep behavior under different multiaxial loading conditions by performing torsion tests, biaxial-planar tests, triaxial creep tests using servo hydraulic testing systems. He and former PhD students designed and fabricated the biaxial and triaxial equipment on their one, twenty years ago.

Prof. Dr. Takamoto Itoh
Ritsumeikan University
Faculty of Science & Engineering
Department of Mechanical Engineering
Chair: Strength of materials under multiaxial loading

Prof. Itoh is working in the field of multiaxial low cycle fatigue for 20 years. He did his PhD in the laboratory of Prof. Sakane on multiaxial low cycle fatigue of AISI304 stainless steel und proportional and nonproportional loading by using cruciform specimens and hollow cylinder specimens at high temperature and room temperature, respectively. His laboratory is carrying out fatigue tests under multiaxial loadings by using servo hydraulic torsion machines 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. The fatigue tests were mainly performed under multiaxial loading at room and high temperatures. 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
