Vibratory Stress Relief Equipment
“FORMULA 62” Vibratory Stress Relief Equipment "FORMULA 62" Vibratory Stress Relief Equipment offers a number of advantages RESIDUAL STRESSES DEFINED over the older thermal stress relieving One of the major problems encountered in the metalworking technique: industry is the build up of stresses that cause distortion and loss of dimensional stability. Anyone involved in • metalworking, whether they are a steel fabricator, The equipment is compact and portable, manufacturer of machine tools or mold maker, can experience and can easily be moved to any location problems holding dimensional tolerances in their workpieces. on the production floor for on-the-job stress relieving The technical definition of residual stress is any stress in an elastic body that is free from external force or restraint and • temperature gradients (changes). A common cause of The investment cost is low, as are the residual stress is an incompatibility between adjacent regions operating and maintenance costs of the metal that can distort neighboring regions. • Short process time, ranging from 15 to Stresses cause distortion in metal when they are unequal. 30 minutes per location depending on the Heavy stresses on one side of a piece of metal will cause movement or distortion. If the stresses are the same all weight and configuration of the through the metal, even heavy stresses will not cause component or fabricated structure movement. The higher the imbalance of stresses, the greater the movement. If the imbalance is high enough, the grains • Easy to use with no extensive operator become permanently distorted and the workpiece cannot be instructions required returned to its previous condition by stress relieving. -

For many people involved in the metal- working trades, the subject of stress relief is something they are not well versed in. As a result, stress relief is a subject they would just as soon like to avoid. With a little technical assistance, the average layman can get a basic understanding of residual stresses and how to deal with them. With this knowledge, he will be better prepared to evaluate shop problems and find a |solution that is effective. The following information is designed to answer some of the most frequently asked questions about stress relieving. Residual stresses, by definition, are introduced into the material in one or How Does It Work? those stresses in an elastic body that is free more of the following ways: thermal, from external force or restraint and metallurgical, mechanical and chemical. Low frequency vibrations are used as a carrier temperature gradients. An incompatibility Since these are the processes that make to deliver high amplitude energy to a metal of regions in the metal created by up our metalworking trades, it is only fabrication, or machined part. The non-homogenous plastic deformation is the right to assume that, at some point in heavy vibrations produce a load that is principal cause of these internal stress time, a stress relief treatment may be superimposed on the existing stress patterns systems, whether they are in an required. -

Bios and Abstracts of RSC Speakers
Colin Bain graduated in Natural Sciences from Cambridge before crossing the Atlantic to undertake his PhD at Harvard with Prof. George Whitesides. He then returned to Cambridge as a Royal Society Fellow, working with Dr. Paul Davies to set up the UK’s first sum-frequency spectrometer. In 1991 he moved to Oxford as a University Lecturer and Fellow of Magdalen College. In 2005 he took up his current position of Professor of Chemistry at Durham University. His research interests lie principally in the chemistry and physics of interfaces, with applications in detergents, personal care products, printing, spraying and lubrication. Prof. Bain has received the Harrison, Corday-Morgan and Tilden Prizes from the Royal Society of Chemistry as well as awards in Japan and Australia. In 2005 he was honoured to deliver the annual McBain Lecture at the National Chemical Laboratory in Pune. He has collaborated with the Indian Institute of Science in Bangalore for a number of years and currently holds a joint UKIERI award with the IISc. Professor Colin Bain Since 2008, he has been a Director of the Institute of Advanced Study at Department of Chemistry Durham – an institute that seeks to promote interdisciplinary dialogue Durham University and research collaborations across the humanities, sciences and social South Road sciences.

It employs over 10,000 staff and has a student population of over 21,000. Most staff are directly appointed and managed by one of the University’s 130 departments or other units within a highly devolved operational structure - this includes 5,900 ‘academic- related’ staff (postgraduate research, computing, senior library, and administrative staff) and 2,820 ‘support’ staff (including clerical, library, technical, and manual staff). There are also over 1,600 academic staff (professors, readers, lecturers), whose appointments are in the main overseen by a combination of broader divisional and local faculty board/departmental structures. Academics are generally all also employed by one of the 38 constituent colleges of the University as well as by the central University itself. Our annual income in 2010/11 was £919.6m. Oxford is one of Europe's most innovative and entrepreneurial universities: income from external research contracts exceeds £376m p.a., and more than 70 spin-off companies have been created. -
