Abstract: An experimental study of riblets with extra thin fins (5 μm thick) is presented. A drag reduction of 2–3 percent per quarter conduit wall is indicated when h+ is around 3–15 in a square ...

Abstract: This paper presents a dynamic analysis of the ultrasonic machining process based on impact mechanics. Equations representing the dynamic contact force and stresses caused by the impinging of ...

Abstract: Explicit expressions are obtained for the stress and displacement fields near the tip of a rigid line inhomogeneity subjected to an inclined loading. It is shown that the tip stress field, ...

Abstract: Vegetation and erosion are a pair of competing and interactive factors that affect the quality of watershed ecosystems. The objective of this study is to develop an innovative approach for conceptualizing and simulating ...

Abstract: This paper describes the results of short-term bending tests on glued laminated bamboo (glubam) and concrete composite (BCC) beams. Four types of connection details were designed and tested: continuous steel mesh (SM), ...

Abstract: This paper presents the experimental results obtained from the testing of nine 1:3 scale square-shaped column specimens. Characteristics of the specimens are low-lateral confinement, low-to-moderate shear span, and high-axial ...
