Investigate the stress distribution in pipework to help evaluate designs.

Your report should be a succinct account of how you approached both parts A & B and what you discovered (10 pages maximum). The following is a rough indication of the expected
content.
1. You should explain your thought processes and reasoning behind your mesh design(s)
rather than describe the ANSYS commands in detail.
2. You should demonstrate how you interpreted the FEA results and compared them with
theoretical expectations. You are free to compare results obtained by other students but you must reference their work.
3. You should explain how you used the ANSYS error estimation facilities to effect change and report the outcome of your actions.
4. Remember to reference all work that is not your own.

Report : Finite Element Analysis (FEA)

Introduction
You are a design engineer working for a heating company, which produces piping for heating
systems. Your company would like you to investigate the stress distribution in some of its
pipework to help evaluate designs.

Instructions
A pipe which is part of a heating system could be described as a thick walled cylinder which
has internal and external diameters of 120 mm and 420 mm respectively. It is made from a
ductile elastic material of your choice and is used to contain hot water at a constant pressure
coming from the outflow of a radiator system.
You need to use your skills in stress analysis to determine the relationship between internal
pressure of the water and the stress in the pipe wall.

Main Investigations

Part A; Standard Pipe
Carry out a finite element analysis to determine the stress distributions across the cylinder
wall when the internal pressure reaches a value, which will cause the material to start yielding
according to an appropriate elastic failure criterion. You are not expected to take temperature
effects into account in your analysis.
