Abstract: Massively parallel molecular dynamics (MD) simulations have been performed to understand the plastic deformation of metals. However, the intricate interplay between the deformation mechanisms and the various material ...

Abstract: For a fully hardened steel material, hole surface microstructures are often subject to microstructural transition because of the intense thermomechanical loading. A white layer can be formed on the surface of a drilled ...

Abstract: The effect of temperature on flow and pollutant dispersion around an isolated building was investigated by computational fluid dynamics. First, the accuracy of the standard

Abstract: Recently, orthogonal cutting has been exploited as a means for producing ultrafine grained (UFG) and nanocrystalline microstructures for various metal materials, such as aluminum alloys, copper, stainless steel, titanium ...

Abstract: Materials often behave in a complicated manner involving deeply coupled effects among stress/stain, temperature, and microstructure during a machining process. This paper is concerned with prediction ...

Abstract: The Office of Inspector General has recently investigated many fraud cases in the disadvantaged business enterprise (DBE) program of the USDOT. The DBE program was established by the USDOT in 1983 to provide an equal ...

Abstract: In order to create interior multiclimate zones suitable for plant cultivation in a solar chimney project proposed for the World Horticultural Exposition 2016 in China, the numerical investigation is performed to a solar ...

Abstract: In order to understand the engineering properties of soil reinforced by short polypropylene fiber, a series of tests were carried out to study the effect of fiber content and fiber length on the strength of the fiber-reinforced ...

Abstract: An adaptive nonlinear synchronization control approach is developed for multiple spacecraft formation flying with elliptical reference orbits. It can guarantee that both the tracking errors and ...

Abstract: An abnormal friction law refers to the case where the friction force does not increase monotonically with the normal pressure. We investigate the possibility of abnormal tribological behavior ...
