Abstract: A weakest-link theory is proposed for analyzing the rate of fatigue crack growth. The joint probability density of a fatigue crack growing an amount X between x and x+dx, and in time η ...

Abstract: This paper investigates fatigue strength of plain concrete subjected to flexural loading. This type of fatigue loading is of concern in the design of concrete bridges and concrete pavement slabs, since the flexural stresses ...

Abstract: The flexural behavior of reinforced concrete beams containing steel fibers is investigated in the present study. An experimental program was set up and nine reinforced concrete beams have been tested, including two series ...

Abstract: The mixed-lubrication problem is formulated as a nonlinear generalized complementarity problem in which the pressure acting on the load-bearing surface is taken as the unknown, and the lubricant ...

Abstract: A numerical method has been developed for solving the nonlinear differential equation which arises in the elastohydrodynamic contact of bearing surfaces. This method is based upon the finite ...

Abstract: A theory was proposed to explain the generation of side thrust in a needle bearing. A quasi-static analysis was performed, which considers the deformation and the equilibrium of the various ...

Abstract: Unexpected combustions dispersion due to variations in fuel quality, production tolerance, and aging of components results in the deterioration of engine performance and increases harmful emissions. Many researchers have ...

Abstract: A hydrogenfueled twostroke prototype demonstrator based on a 9.9 hp (7.4 kW) production gasoline marine outboard engine is presented, which, while matching the original engine's rated power output on hydrogen, achieves ...
