Publikováno v: Journal of Dental Sciences, Vol 19, Iss 4, Pp 2114-2125 (2024)
Background/purpose: Bone morphogenetic protein-9 (BMP-9) has demonstrated multiple advantages in promoting osteogenesis. Our previous findings have indicated that the use of an absorbable collagen membrane (ACM) as a carrier for growth factors is eff

Validation of the applicability of the best-fit fatigue curves for 550 °C in Mod.9Cr-1Mo steel to 1×1011 cycles
Autor: Kodai TOYOTA, Yuya IMAGAWA, Takashi ONIZAWA, Shoichi KATO, Yoshiyuki FURUYA
Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 89, Iss 928, Pp 23-00206-23-00206 (2023)
In order to design fast reactors, it is necessary to consider high cycle fatigue of structural materials up to 1×109 cycles. Since the fatigue usage factor (UF) is calculated down to the order of 0.01 in fast reactor design, it is necessary to devel

Development of creep property equations of 316FR stainless steel and Mod.9Cr-1Mo steel for sodium-cooled fast reactor to achieve 60-year design life
Autor: Takashi ONIZAWA, Ryuta HASHIDATE
Publikováno v: Mechanical Engineering Journal, Vol 6, Iss 1, Pp 18-00477-18-00477 (2019)
316FR stainless steel and Mod.9Cr-1Mo steel are candidate structural materials for the present design of sodium-cooled fast reactor (SFR) in Japan. A number of research works have been performed in Japan to develop the SFR for practical use. Aiming a

Proposal of Simulation Materials Test Technique and Their Constitutive Equations for Structural Tests and Analyses Simulating Severe Accident Conditions
Autor: Takashi Wakai, Shoichi Kato, Takashi Onizawa, Ryuta Hashidate, Naoto Kasahara
Nuclear structure’s integrity must be confirmed under severe accident conditions. However, performing structure tests using actual steels is very difficult and expensive. Therefore, the authors conducted structure tests using the lead alloy to eval

Evaluation of the Japanese Fatigue Test Data in Gr.91 for Elevated Temperature Design
Autor: Takashi Onizawa, Masanori Ando, Kodai Toyota, Ryuta Hashidate
Publikováno v: Volume 1: Codes and Standards.
The ASME Boiler and Pressure Vessel Code (ASME BPVC) Section III, Division 5, Subsection HB, Subpart B provided only one design fatigue curve for Grade 91 steel (Gr.91) at 540 °C (or 1000 °F) in 2019 and earlier versions. To overcome this disadvant

Proposal of Simulation Material Test Technique for Clarifying the Structure Failure Mechanisms Under Excessive Seismic Loads
Autor: Shoichi Kato, Ryuta Hashidate, Naoto Kasahara, Takashi Onizawa, Takashi Wakai
Publikováno v: Volume 2: Computer Technology and Bolted Joints; Design and Analysis.
This paper proposes simulation material test technique using 99% lead - 1% antimony alloy instead of actual structural material. It is very essential to clarify the structure failure mechanisms under excessive seismic loads. However, structural tests
