Surface Roughness Investigation and Stress Modeling by Finite Element on Orthogonal Cutting of Copper

To study the surface roughness of commercially pure copper, a modern non-contacting optical technique was used in this work. The finite element (FE) technique was applied by simulating the machining process to predict the stress during orthogonal cutting. The experimental work focused primarily on the impact of the cutting speed (N) and the feed rate…

Complex Eigenvalue Analysis of Railway Wheel/Rail Squeal: Advanced Study

Wheel/rail squeal noise of trains is one of the challenging problems to be solved. Several models such as self-excited instable vibration due to negative damping, flutter instability, hammering effect due to local defects, etc. were proposed, but a successful model for the squeal problem has not been presented until now. In this study, experimental and…
