WRC Bulletins contain final reports from projects sponsored by the Welding Research Council, important papers presented before engineering societies and other reports of current interest.Bulletin 537 is intended to facilitate implementation of the widely required and used relations found in the March 1979 Revision of WRC 107 for local stresses in spherical and cylindrical shells due to external loadings. The original analytical and experimental work of WRC’s Pressure Vessel Research Council delivered has become the an essential tool for pressure vessel design for 45 years and in its present form for over 30 years. In response to numerous requests over the years for the precise equations depicted in the figures in the 1979 version of WRC 107, WRC 537 has been prepared. The objective was to eliminate potential errors in implementation, facilitate proper interpolation and extrapolation and permit efficient computation with modern computers
Mike Straub offered WRC his work at digitizing the numerous curves found in WRC 107. Mr. David A. Osage organized an extensive effort to precisely capture the details of each and every curve in each and every figure and develop the complex mathematical relations which render the new document useful for modern engineering practice. The effort and assuring the accuracy of the results required a great deal of time and attention to details. Involved in developing the equations and checking the results on Dave Osage’s team were Mary Buchheim, David Amos, Tiffany Shaughnessy and Debbie Samodell.
WRC will no longer deliver WRC 107 when requested for purchase. WRC 537 provides exactly the same content in a more useful and clear format. It is not an update or a revision of 107. It is the 2010 printing of WRC 107. It has been meticulously checked. Those responsible for codes, standards and specifications
that require use of WRC 107 should amend those documents to reflect the fact that WRC 537 is the equivalent to WRC 107 and provides the same acceptable basis for design.
Since the 2010 edition of WRC Bulletin 537 three Errata’s have been issued. The first Errata was issued in April 2011, the second Errata was issued on June 27, 2011 and the third Errata issued on August 19, 2011. Third Errata issued in August of 2011 was accumulative.
