Stress rupture predictions of pressure vessels exposed to fully engulfing and local impingement accidental fire heat loads

Experiments have shown that pressure vessels made of ASME SA 455 steel can fail by high-temperature stress rupture in less than 100min when exposed to accidental fire heat loads. The objective of this work is to develop a three dimensional finite element analysis (FEA) model capable of predicting structural failure in pressure vessels to assess the effects that various parameters have on vessel failure. These parameters included wall thickness, …
