Abstract:
New development in material fabrication resulted in functionally graded materials (FGM) with properties, can vary continuously based on the desired purpose. Vast applications of these materials attracted scientists to extend the researches in this area. One of the promising applications of these materials is in the optimized spherical and cylindrical pressure vessels. Optimization is usually based on the minimization of heat transfer and maximization of the strength of the vessel under pressure. In the present dissertation, spherical and cylindrical pressure vessels are designed and characteristics of the material distribution for certain pressure and temperature is developed. In this process a cylindrical superelement along with a spherical superelement are used to evaluate the optimized temperature and pressure distribution for a certain material properties in these vessels
