Abstract: A particular formulation of the three-dimensional finite element method specifically for analyzing the Vickers hardness test is established. The Vickers hardness of 0.46 percent carbon steel and ...

Abstract: Active vibration control requires a velocity signal which is fed back to the force actuator to produce the damping force to the structure. Usually a gap sensor is used to detect the displacement ...

Abstract: Rail dark spot defect, also termed squat failure or shelling, which is a kind of rolling contact fatigue failure and occurs frequently on running surfaces of railway rails carrying high speed ...

Abstract: In a previous paper the authors showed that when the surface velocity of a body having lower elastic modulus is faster than that of a body having higher elastic modulus, and when the radius ...
