Analysis of the Rotary-draw Bending Process for Thin-walled Rectangular Aluminum Tube
The Rotary-Draw Bending (RDB) process is a distinguished process employed for the precision cold bending of a hollow tube with small radius bends using Numerical Control (NC) machines. This research presents an analytical model based on the power law hardening model for the RDB processing of rectangular thin tubes. Based on the constraints of the tube in the dies and its thinness, the plane str...
متن کاملMovers and Shakers
Most projects, in most walks of life, require the participation of multiple parties. While it is difficult to unite people in a common endeavor, some people, whom we call “movers and shakers,” seem able to do it. The paper specifically examines moving and shaking of an investment project. We analyze a model with a large number of ex ante identical agents. Agents form social connections, bid to ...
متن کاملStrobe Lights, Pillow Shakers and Bed Shakers as Smoke Alarm Signals
This paper assesses the waking effectiveness of strobe lights and pillow and bed shakers as smoke alarm warning devices and compares them to an auditory signal. The signals were activated at increasing intensity levels during slow wave (deep) sleep in two groups, (i) 38 adults aged 18-77 years with hearing loss of 2570 dBA in both ears, and (ii) 32 young adults aged 18 -26 years impaired with a...
متن کاملEffect of rotary friction welding variables on mechanical and physical properties of aluminum-copper tube joints
The aim of this study is to investigate the effect of rotary frictional welding process variables on microstructure, mechanical and physical properties of copper-aluminum dual-tube pipes. For this purpose, using a thermosetting friction welding machine, a copper pipe (99.44% purity) with a similar diameter aluminum tube (1050), was welded in three different conditions with different friction pr...
