Engineering definitions of small crack and long crack at fatigue limit under tensile mean stress and a prediction method for determining the fatigue limit of a cracked Mg alloy
Autor: Takuya Kinoshita, Hiroshi Noguchi, Toshiyuki Ishina, Shigeru Hamada, Komei Hayashi, Kazunori Morishige
Publikováno v: International Journal of Fatigue. 56:86-94
A simple method was proposed for evaluating the influence of mean stress on the fatigue limit of a cracked specimen using engineering approximations. Three types of crack sizes were introduced for evaluation: an “extra small crack,” a “small cr

Simple calculation method for stress concentration and stress intensity of T-shaped member
Autor: Komei Hayashi, Hiroshi Noguchi, Mitsuji Ueda, Shigeru Hamada
Publikováno v: International Journal of Mechanical Sciences. 75:8-15
The objective of this study is to clarify the influence of shape parameters on the stress concentration in simple forms. In recent years, by the spread of general purpose Finite Element Method (FEM) analysis software, anyone can carry out FEM analysi

Effect of Friction Stir Welding Condition on Fatigue Limit of Welded Non-Combustible Mg Alloy
Autor: Hiroshi Noguchi, Komei Hayashi, Ichinori Shigematsu, Shigeru Hamada, Michiru Sakamoto
Publikováno v: Key Engineering Materials. :311-314
The atigue strength of Friction Stir Welding is affected by the structure and the welding defect size. The welding defect sizes have a scatter. Therfore, the effect of Friction Stir Welding condition on fatigue limit of welded noncombustible Mg alloy

Proposed Strength Evaluation Method for Casting Material with Defects (Using Non-combustible Mg Alloy with Added-Si)
Autor: Matsumoto Toshiharu, Hiroshi Noguchi, Shigeru Hamada, Komei Hayashi, Michiru Sakamoto
Publikováno v: Journal of Solid Mechanics and Materials Engineering. 5:534-545
In order to evaluate a casting material which had a variable tensile strength, a strength evaluation method was proposed. Tensile tests were carried out on a specimen with a particular artificial defect as the fracture origin. The fracture origin siz

Proposed Simple Determination Method for Welding Condition of Joint from Fatigue Limit Characteristics (1st Report: Application to TIG-Butt-Joint of Non-combustible Mg Alloy)
Autor: Taka-aki Kawazoe, Shigeru Hamada, Hiroshi Noguchi, Mitsuji Ueda, Michiru Sakamoto, Komei Hayashi, Harumi Morita
Publikováno v: Journal of Solid Mechanics and Materials Engineering. 5:409-424
The non-combustible Mg alloy is useful as a structural material because of its high specific strength and high ignition point, but its suitable welding conditions have not been established for manufacturing floors. In this study, a simple evaluation
