Pipe stress analysis provides the necessary technique for engineer to design piping systems without overstressing and overloading the piping components and connected equipment. The following slide from applied mechanics are briefly discussed (not defined) to familiarize with them. To make easy complexity of piping analysis either in boiler/power plant structure or offshore structure and its facilities, we may use Caesar II to help engineer analyze piping system. Special thanks to Dr. I Wayan Suweca, my mentor who teach me Caesar II.
