Autor: Toshihiko Sakagami, Toshimune Imai, Atsuo Senga, Shigeji Yamada, Toshimitsu Nozu, Kiyoshi Yoshida

Publikováno v: 2018 17th International Conference on Ground Penetrating Radar (GPR).

In recent years, there are many accidents caused by roadway cave-ins where the roads were constructed in the past. So the GPR is used as a way to detect the underground cavities for preventing accidents in the future. In the past, when handheld GPR w

Effect of Loading Conditions and Material Properties on the Relation between Crack Opening Distribution and Fatigue Crack Growth Rate

Autor: Shigeji Yamada, Takahiro Teranishi, Satoshi Tanaka, Hironobu Nisitani, Naosuke Takao

Publikováno v: TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A. 64:859-863

Fatigue crack growth tests were carried out on an annealed, pre-strained or quenched-and-tempered 0.45% carbon steel under rotating bending or reversed torsion. Crack opening displacement ranges (ΔCOD's) along a crack were measured in the neighborho

Characteristics of Fatigue Crack Growth of Extruded Aluminum Alloy in Oil Environment

Autor: Hironobu Nisitani, Satoshi Tanaka, Norio Miyagi, Shigeji Yamada, Norio Kawagoishi

Publikováno v: TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A. 60:2037-2041

Rotating bending fatigue tests were carried out on specimens of an extruded aluminum alloy and a drawn aluminum alloy in air and in oil in order to investigate the effect of the oil environment on the fatigue strength. In the drawn aluminum alloy, th

Effect of Oil Environment on the Fatigue Crack Growth of Al Alloy Specimens with a Small Blind Hole under Torsional Loading

Autor: Kazuhiro Kitamura, Shigeji Yamada, Norio Kawagoishi, Norio Miyagi, Satoshi Tanaka

Publikováno v: TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A. 59:2265-2270

In order to investigate the influence of oil on crack growth behavior, torsional fatigue tests were carried out on three kinds of age-hardened Al alloy specimens, 2017-T4 extruded, 20l7-T4 drawn and 7075-T6 extruded, with a small blind hole, in air a

SYNTHESIS AND STRUCTURE OF 4-PHENYL-1,3,4,4H-THIADIAZIN-5(6H)-ONE

Autor: Toshiyuki Nakanura, Yoshio Matsubara, Masakuni Yoshihara, Shigeji Yamada, Toshihisa Maeshima

Publikováno v: Phosphorus and Sulfur and the Related Elements. 16:89-96

4-Phenyl-1,3,4,4H-thiadiazin-5(6H)-one 2 was synthesized by the reaction of methyl carboxylatomethyl-N-anilinothioformimidate 1 with triethylamine in methanol and the structure of 2 was determined by X-ray analysis. The mechanism of formation of 2 is
