Abstract: The tangential contact stiffness of cylindrical asperities is investigated using macroand micromechanisms in this study. A microanalysis model is developed and the tangential contact stiffness of elliptically parabolic ...

Abstract: Vibration-based methods are promising for damage identification; however, their capabilities for damage identification under temperature variations are usually limited. In the paper, a vibration-based nondestructive global ...

Abstract: Flexible base asphalt pavements have been used widely in high grade roads in China. The fatigue performance is one of the most important properties for asphalt-treated base mixtures. Firstly, five kinds of asphalt mixtures ...

Abstract: Equi-amplitude fatigue loading experiments on five reinforced concrete T-beams were conducted to observe the fatigue damage development. Three stages of fatigue damage were seen in the experiments. The damage rapidly ...
