Abstract: The global drive to limit the effects of climate change affords a strong incentive to reduce CO2 emissions. H2 is one of the cleanest energy sources, because its combustion does not produce CO2. It is well known that NH3 ...

Abstract: Previously, it has been verified experimentally for durations of impact that the Hertz theory (the quasi-statical theory) holds during impact of spheres without any exception. However, no measurement ...

Abstract: The prevailing Hertz theory in contact and in impact is based on the total compressive displacement of a semi-infinite elastic body. This paper considers displacements of finite elastic medium ...

Abstract: The fatigue behavior of weathered welded specimens of weathering steel (JIS SMA50) and structural steel (SM50) was investigated. Sixty‐six (66) stiffener specimens and 62 gusset specimens were tested under constant amplitude ...

Abstract: A practical use of the isotache concept in creep settlement prediction is newly introduced in this study. The isotache concept introduces a unique relationship between the strain and the consolidation pressure corresponding ...

Abstract: This paper addresses the modeling and prediction of the normal holding force in an electromagnetic chuck used in precision machining applications. Knowledge of the normal holding force is necessary ...

Abstract: The whirl instability occurs at higher rotating speeds for a full circular fluid-film journal bearing, and many types of clearance configuration have been proposed to solve this instability ...

Abstract: In order to simulate the effect of drainage on soils adjacent to gravel drains that are installed as countermeasure against liquefaction, several series of cyclic triaxial tests were performed on saturated sands under ...

Abstract: A prediction system with a oneregion (1R) model was developed to predict water temperature in a spent fuel pit (SFP) after the shutdown of its cooling systems based on threedimensional (3D) thermalhydraulic behavior computed ...
