This tutorial provides a step-by-step demonstration for EN 12952-3 fatigue analysis using Fatigue+ and ANSYS result (.rst) file.
A tube in a heat exchanger goes through a thermal loading process. The process is defined as an event. A fatigue analysis is required to determine number of such process event that the tube can survive. The tube is EN 10216 seamless tube with material designation X10CrMoVNb9-1. Wall thickness of the tube is 12 mm. Surface condition of the tube is that peak-to-valley height Rz = 30 μm.
A transient thermal and structural analysis was done in ANSYS. The name of the result file is file.rst.
Use EN 12952-3 code to calculate fatigue life of this tube.
