Yield onset of thermo-mechanical loading of FGM spherical pressure vessels

In this paper, thick wall spherical tanks made of functionally graded material under internal pressure and temperature gradient are studied. Material parameters have been considered as power functions. They play important role in the elastoplastic behavior of these materials. To clarify their role, different materials with different parameters have been used under temperature gradient. Finally, their effect and loading effect havebeen determined in first yield point. Also, the important role of temperature gradient was also shown
