This project aims to improve the understanding of calculation of the burst speed of rotating discs and to provide updated guidance to engineers working in the field of, amongst others, turbomachinery design. The current approach is based on a 1944 study which found a correlation between the burst speed and the average hoop stress reaching the UTS of the material. Whilst it is fairly easy to demonstrate the error of this approach, it remains in use today albeit with knock-down factors to hopefully ensure that use of the formula remains safe.
RMA is acting as an Independent Technical Editor in a new NAFEMS initiative to increase the interaction between Benchmark Magazine and its readership. This initiative is called The NAFEMS Benchmark Challenge with the first challenge being published in October 2014. A Response to the Challenge will appear in the following issue of Benchmark and during the period between issues readers may collaborate and seek clarification through the Challenge Blog at NAFEMS. The challenges are going to be published in booklets by NAFEMS covering the complete challenges, responses and additional useful information for each year that the challenge continues to run.
