This paper presents the results of a study on how the burst of steel tubes is influenced by elevated temperature between 75°F and 350°F (24°C and 177°C). The study involves experiments and modeling of burst. Burst tests were conducted on UNS S32750 super duplex stainless steel. Part I is concerned with rate independent burst, while part II (to be published) is concerned with rate dependent burst. Two models were used to simulate the burst experiments. In the first model, the tube is represented as a cylindrical expansion membrane. In the second model, the tube is modeled as a finitely deforming shell which allows a bulge to grow in the unsymmetric manner seen in the final stages of the experiments. Both models produce the burst pressure accurately. The second model has the advantage of being able to study the effect of local thickness imperfections.
