Investigations on strength of piping for non-condensable gas combustion (Part 3: Estimation of fracture strain of steel pipes subjected to hydrogen-oxygen detonation)

Autor: Akira NEBU, Koji YAMADA, Koji DOZAKI, Akitaka HIDAKA, Masahiro UCHIDA, Takahiro SONE

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 81, Iss 827, Pp 15-00063-15-00063 (2015)

To assess the integrity of piping under the detonation pressure of accumulated hydrogen-oxygen, the fracture strain of the pipe material must be identified. In carbon steel pipe specimens that had been experimentally ruptured by hydrogen-oxygen deton

Investigations on strength of piping for non-condensable gas combustion (Part 2: FEM analysis of steel pipes with a valve or an elbow subjected to hydrogen-oxygen detonation)

Autor: Akira NEBU, Koji YAMADA, Koji DOZAKI, Akitaka HIDAKA, Masahiro UCHIDA, Takahiro SONE

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 81, Iss 827, Pp 14-00665-14-00665 (2015)

Carbon steel pipe specimens, which had been experimentally ruptured or deformed by hydrogen-oxygen detonation, were analysed by dynamic analysis using a finite element method (FEM). Pressure load histories induced by detonation were estimated by comp

Low cycle fatigue behaviors of elbow pipe with local wall thinning

Autor: Akitaka Hidaka, Katsumasa Miyazaki, Kotoji Ando, Masakazu Hisatsune, Yoshio Urabe, Sota Watanabe, Koji Takahashi

Publikováno v: Nuclear Engineering and Design. 239:2719-2727

Low cycle fatigue tests were conducted using 100A elbow specimens made of STPT410 carbon steel with local wall thinning. Local wall thinning by erosion/corrosion was simulated by machined pipe wall thinning. The local wall thinning areas were located

Effect of Local Wall Thinning on Low-Cycle Fatigue Behaviors of Elbow With Internal Pressure: Estimation of Fatigue Life Based on Revised Universal Slope Method

Autor: Katsumasa Miyazaki, Kazuya Matsuo, Kyohei Sato, Yoshio Urabe, Masakazu Hisatsune, Akitaka Hidaka, Kotoji Ando, Koji Takahashi

Publikováno v: ResearcherID

Low-cycle fatigue tests and finite element analysis were conducted using 100A elbow specimens made of STPT410 with local wall thinning in order to investigate the influences of local wall thinning on the low-cycle fatigue behaviors of elbows with int
