Abstract: This paper presents a finite element model of orthogonal machining by using a 2-node link element to simulate chip separation. The chip and workpiece are connected by these link elements along ...

Abstract: Chatter is one of the critical issues in a machining process since it deteriorates the surface quality of a workpiece and reduces machining efficiency. A new method is developed to suppress ...

Abstract: Hybrid fiber-reinforced polymer (FRP)–concrete–steel double-skin tubular columns (DSTCs) consist of an outer FRP tube and an inner steel tube, with the space between them filled with concrete. Many experimental studies ...

Abstract: Concrete-filled fiber-reinforced polymer (FRP) tubes (CFFTs) are an attractive form of hybrid compression members incorporating FRP. CFFTs have several advantages over traditional column forms, including their excellent ...

Abstract: Shallow turbulent flows were produced in a tank of small thickness to study the friction effects on large-scale turbulent motion of small depth. The tank was constructed of two parallel walls. The space between the parallel ...

Abstract: A novel seam tracking technology based on high frequency ultrasound is developed in order to achieve high accuracy in weld seam identification. The transmission efficiency of the ultrasound is ...

Abstract: The welding industry is driven to improve productivity without sacrificing quality. For thick material welding, the current practice is to use backing or multiple passes. The laser welding ...

Abstract: The transverse motion of a saw-wire affects the cutting surface geometry in wire-saw slicing. To evaluate the magnitude of the wire transverse motion under no-slurry and no-workpiece conditions, ...

Abstract: This paper presents a systematic model for the operation simulation and optimization of a novel multi-mode hybrid powertrain. The hybrid configuration proposed in the paper features a planetary ...
