Abstract: Time dependent thermal EHL circular contact results with measured surface roughness were obtained to analyze the effects of roughness on pressure, film thickness, temperature, and coefficient of ...

Abstract: This paper explores the beneficial use of low-reactivity coal fly ashes as cementitious binder in mortars without heat activation. A uniform design scheme was employed for the statistical design of experiments. Predictive ...

Abstract: A finite element model was developed to investigate the effects of a spherical debris on elastohydrodynamically lubricated rolling/sliding contacts. Three dimensional dent profiles were obtained ...

Abstract: Dents in elasto-hydrodynamic lubricated (EHL) contacts will initiate spalls and shorten the fatigue life significantly. Experimental results are provided from a ball-on-rod rolling contact fatigue ...

Abstract: This study aimed to investigate the corrosion characteristics of concrete exposed to water environments containing aggressive CO2. Ultrasonic velocity and quality tests were conducted to examine the deterioration law, and ...

Abstract: Pin joints are widely used connections for hanger assembly in suspension bridges. Significant rotary motions have been observed between pin rods and the connected members for long-span bridges subjected to traffic and ...

Abstract: This paper aims to investigate the distribution characteristics of the partial carbonation zone of concrete. A series of experimental carbonation tests considering the effect of external temperature, concentration of CO2, ...

Abstract: A new approach, steady micro air injection from the casing, is proposed to improve the stability of a three-stage low-speed axial compression system. Although the injection rate is designated ...

Abstract: Several large-magnitude earthquakes, including the Prince William Sound earthquake of March 1964 and the Denali earthquake of November 2002, occurred in the state of Alaska and caused considerable damages to its transportation ...
