CNG storage well IRIS fatigue failure finite element method limit load The purpose of the present work is to research the feasibility of IRIS used in detecting storage well and to assess the casing with inner surface...

... steel. The correlation between fatigue failure and energy is confirmed from the vibration experiment. Therefore it is expected that time for fatigue failure can be evaluated by the energy balance equation. Changes in response (stainless steel, 0.130 m, 15.2 Hz, and Wave 2) Figure 5 shows...

...Young H. Park; Jun Tang This paper introduces a maintenance decision-making strategy in the general area of replacement and reliability of mechanical components. The decision-making strategy involves the optimization of replacement interval calculated from fatigue failure of mechanical components...
