... behavior of pipe flange connections at elevated temperature, by incorporating the stress–strain curves of sheet gaskets measured in the temperature range which covers its usual service condition. Then, the reduction rate of bolt preloads at elevated temperature is systematically evaluated. The analytical...

...Guillermo Ramirez; Paul H. Ziehl; Timothy J. Fowler A research program evaluating the effect of elevated temperature in the acoustic emission testing of fiberglass vessels was completed recently. The program aimed at evaluating the current ASME provisions that require acoustic emission testing...

... for a small change in time domain length. Oscilloscope traces (V versus μ s ) for signals from receiver with gain adjusted to keep signals approximately the same height. The transducer was mounted on a 25 mm thick steel sample and tested in pulse-echo repeatedly to elevated temperature...

... subjected to acoustic emission evaluation at elevated temperature. This has lead to speculation regarding the appropriateness of conducting acoustic emission evaluations at elevated temperature. To address these issues an experimental investigation was conducted on representative coupon specimens...
