Let’s consider, for example, a fully pressurized pressure vessel with a load applied on the nozzle as shown in the picture. This load creates a bending stress (secondary stress) at the nozzle-to-head juncture. In the left-hand side of the nozzle, this load creates a tension strain value ε1 (see below), somewhat beyond the yield strain […]

Fatigue analysis is often more demanded for Pressure Vessels and Shell and Tube Heat Exchangers (S&T). Operating conditions involving pressure and/or temperature cycles could result in a fatigue analysis requirement. Previous to perform a fatigue analysis is necessary to run screening criteria in order to check according to ASME VIII Div. 2 Ap. 5.5. if […]
