Abstract: A mathematical model was developed for calculating the temperature, stress-strain field, and their interaction in a metallic material undergoing phase transformation during quenching processes. The ...

Abstract: The objective in this research is to develop a mathematical model which simulates the grinding process and predicts the transient temperature field and the stresses generated in the workpiece ...

Abstract: The determination of the elastoplastic behavior of multiphase materials such as metallic alloys or steels during phase transformation is a complex problem. This incremental method is aimed at ...

Abstract: The wear rate of cast iron and the corrosion potential (Ecorr) and current (Icorr) were measured in sulphuric acid in order to study the mechanism of corrosive wear of cast iron. The corrosive ...

Abstract: This paper presents a machining accuracy analysis for computer-aided fixture design verification. While discussing the utilization of CNC machine tools and machining centers, machining errors are ...

Abstract: In recent years, many applications in precision engineering require a careful isolation of the instrument from the vibration sources by adopting active vibration isolation system to achieve a ...

Abstract: Plug flow of coarse particles was investigated experimentally in a horizontal pipe, in which a sub-pipe for secondary air injection was installed. Measurements were made about the plug motion, ...

Abstract: The limit of rotating stall was experimentally determined for three very small specific speed centrifugal blowers. The impellers were specially designed for stall-free at very small flow rates, ...

Abstract: This paper concerns certain aspects of wave propagation in composite materials reinforced by fibers whose directions vary continuously in space. Special attention is focused on the case of slight ...
