I am trying to run FEA on an adapter assembly but I am having issues with fixing the end conditions. The Stress is high since it is trying to hold a pipe that needs to expand. These end conditions have to be fixed/fixed guided in order to determine the correct results. Anyone have an answer?
Adapter material: 4140 steel
Ambient Temperature: 68 degrees F
Thermal load: 500 degrees F
Fixtures analysis 1: Fixed, Guided sliding connection with x and z axle restrained.
Pipe wall thickness: .38”
Pipe ID: 1.25
Results required: Displacement, safety factor and resultant forces.
