Kuk c چکیده: Purpose: Over the last few years, there has been a growing interest in quantitative representation of heat transferand fluid flow phenomena in weld pools in order to study relationships between the processing variables andthe quality of the weldment produced and ...
مقاله جوشکاری با عنوان : Finite element analysis of resistance spot welding process Guo Zhong چکیده : A coupled finite element model is developed toanalyze the transient thermal and mechanical behaviors ofResistance Spot Welding (RSW) process using commercialsoftware ANSYS. A direct-coupled electrical-thermal FiniteElement Analysis (FEA) is firstly performed to simulate thetransient thermal characteristics of RSW process. The thermalhistory of the whole ...
Seismic Analysis of Structures Copyright copy; 2010 John Wiley amp; Sons (Asia) Pte Ltd Author(s): T. K. Datta While numerous books have been written on earthquakes, earthquake resistance design, and seismic analysis and design of structures, none have been tailored for advanced students and practitioners, and those who would like to have most of the important aspects of seismic analysis in one place. With this book, readers will gain proficiencies in the following: ...

James Roughton, Nathan CrutchfieldButterworth-Heinemann, Apr 8, 2011 - Technology amp; Engineering - 520 pages - pdf A Job Hazard Analysis (JHA) identifies the basic job steps and tasks and their associated hazards and risks, and then develops safe operating procedures and hazard controls based on this analysis. In this book, James Roughton and Nathan Crutchfield argue that the JHA should be the centrepiece of any risk control and occupational safety and health program and a ...
In the current work we obtained exact solution for nonlinear free vibration of nanotubes (NTs) with surface effects incorporated to Euler-Bernoulli beam theory and von Karman geometric nonlinearity. We used Jacobi elliptic functions to obtain the nonlinear natural frequencies. Normalized nonlinear natural frequencies and the phase trajectory were studied with the presence of surface effects. This study might be helpful to design NT-based devices in a wide range of applications. ...
