Type: conference-paper
Abstract: A fatigue of a typical pressure vessel was evaluated using Finite Element Analysis based on ASME Boiler and Pressure Vessel Code Section VIII Division 2. The pressure vessel was subjected to thermal and pressure cyclic loading. A finite element code ANSYS ver. 14.5 was used to perform the linear elastic stress fatigue analysis of the vessel. The vessel was modeled as an 2D axisymmetric model. The fluctuation load of thermal, pressure, dead weight and pressure drop were considered in the analysis. The alternating stress was calculated using the result of Finite Element Analysis. Then from the fatigue curves of material, the permissible number of cycle corresponding to the alternating stress was determined. The fatigue damage was calculated by dividing the actual number of repetitions with the permissible number of cycle. If the accumulated fatigue damage was less than one then the design of the pressure vessel was accepted.
