Prof. Katsuyuki Kida, University of Toyama, Japan
Professor Katsuyuki Kida was born in 1968 in Osaka, where he studied mechanical
engineering at Osaka University from 1988. Apart from course work, he studied rolling
contact fatigue (RCF) occurring in TiC and TiN coated steels using both X-ray
diffraction and scanning acoustic microscopy. After graduation he pursued his academic
career and obtained a Ph.D. in engineering mechanics in 2000, investigating RCF problems
of all-Si3N4 bearings. By observing cracking and flaking failure under RCF, he succeeded
in explaining the material`s features from the viewpoint of fracture mechanics. From
2000 he focused his work on investigating the contact problems of several materials used
in machine elements. He has also continued fundamental research on contact problems, for
which he received ‘The Best Paper Prize (FFEMS PRIZE)’ from ‘Fatigue & Fracture of
Engineering Materials & Structures’ journal in 2005. The awarded papers reported
establishing a crack growth mechanism under contact pressure, a problem previously
unsolved for over 70 years since S. Way’s proposed theory. His research interests now
include the development of three dimensional scanning Hall-probe microscope
technologies, fatigue phenomena in polymer bearing, crack growth mechanism under contact
stresses and refinement of high-carbon steels. 
Prof. Koshiro Mizobe, University of Toyama, Japan
Koshiro Mizobe is a professor in the Department of Mechanical Engineering at the
University of Toyama, Japan. He has published over 50 papers in various research fields
including: evaluation of stress intensity factors, repeated heating, homology evaluation
of microstructure, and polymer bearings. Koshiro studied mechanical engineering at
Kyushu University, Japan, graduating in 2013. He studied the repeated quenching
refinement method of high-carbon chromium steels in his PhD course. For this work he
received the Research Fellowship for Young Scientists in 2013-2014 from the Japan
Society for the Promotion of Science as well as Top Young Researcher Award in 2012 from
Kyushu University. Since 2015 he has been an assistant professor in the Department of
Mechanical Engineering at the University of Toyama. He has won some best paper awards
from international committees (ICMDME, CMPSE and ICMTM) and received some grants (25th
ISIJ research promotion grant from the Iron and Steel Institute of Japan and research
promotion grant from JKA). His current research topics with a brief explanation are as
follows. Repeated heating method Martensitic high-carbon high-strength bearing steel is
one of the main alloys used for rolling contact applications where high wear resistance
is required. Refining the prior austenite grain size through repeated heating is a
process commonly used to enhance the material’s strength. He studied the effect of
repeated heating on the microstructure near inclusions through the rolling bending
fatigue tests. Development of hybrid polymer bearings Koshiro is focusing on polymer
bearings because it is suitable for the no lubricant situation and the corrosive
situations. In particular, he focuses on PEEK which is a tough semi-crystalline
thermoplastic polymer and PTFE which has low friction coefficient. Now, he develops the
combination of PEEK races-PTFE retainer bearings.
Assoc. Prof. Takahiro Matsueda, National Institute of Technology(NIT),Suzuka College, Japan
Takahiro Matsueda is an assistant professor in the Department of Mechanical Engineering
at the University of Toyama, Japan. He has investigated evaluation of fatigue strength
of steel, stress intensity factors of microcrack, nondestructive testing and evaluation
of material strength such as solar cell, ceramics and polymer. Takahiro Matsueda
graduated from mechanical engineering at Kyushu University, Japan, in 2014. He majored
in evaluation method of fatigue strength with notched steel in a PhD course. He was an
assistant professor in the Department of Mechanical Engineering at the Tokyo
Metropolitan University from 2015 to 2019. He has been an assistant professor in the
Department of Mechanical Engineering at the University of Toyama from 2020. He has also
won awards for research from international committees (ICSMMS, ICMEMSCE and ICMTM).
Brief introductions of current research topics are as follows. Nondestructive evaluation
of materials using AE and LT techniques Takahiro Matsueda’s research aims to reveal the
mechanisms of microcrack initiation and accumulation, and their contribution to the
electrical degradation during fatigue fracture. He detected and identified microcrack
initiation using the acoustic emission (AE) and Lock-in thermography (LT) techniques.
The electrical degradation of solar cell was evaluated by monitoring electrical power
calculated from Current-Voltage (I-V) curve. Furthermore, microdamage contributing to
the electrical degradation were identified by Lock-in thermography (LT). He proposed the
method to evaluate microcrack initiation using the AE, LT and I-V curve. Prediction
method of fatigue limit in metal materials Takahiro Matsueda is studying the new
prediction method based on fracture mechanics for safely design. In particular, he
focuses on improvement of the method to define the fatigue crack shape and propagating
during fatigue test.
