In this session we will show how Finite Element Analysis (FEA) is used to ensure safe and optimized design of different subsystems in industrial equipments. We begin with a stress analysis of a pipe under thermal loads. Then we learn how to interpret simulation results to determine the sealing quality of a pressure vessel. Following that, we perform stress analysis of an O-ring incorporating the necessary nonlinear behavior in the simulation. We then proceed to perform a reliability study of a composite overwrapped pressure vessel. We wrap up this session by performing a thermal analysis of a centrifugal pump to obtain the temperature distribution over it when transporting hot fluids.
