Shakedown and Cold Creep of Stainless Steel Type 316 Torispherical Drumheads Subjected to Internal Pressure

The results from cyclic internal pressure tests on two nominally identical stainless steel type 316 torispherical drumheads are presented. The effect of cold creep is investigated and is shown to contribute most of the accumulated strain during pressure cycling. The experimental shakedown pressure i...

Description
Summary:The results from cyclic internal pressure tests on two nominally identical stainless steel type 316 torispherical drumheads are presented. The effect of cold creep is investigated and is shown to contribute most of the accumulated strain during pressure cycling. The experimental shakedown pressure is compared with the design pressures from BS 5500 and the effect of over-pressure testing on subsequent cyclic behavior is discussed.
