I graduated in Master of Science Mechanical Engineering-Applied Design from Islamic Azad University, Ahvaz Branch (IAU). Due to the vast oil and gas resources in developing countries, particularly Iran, optimal use of appropriate materials according to environmental conditions, mechanical and metallurgical properties are very important. Because of this fact, my research focuses on the behavior of advanced composite materials, particularly Functionally Graded Material during environmental conditions or working conditions are changing. In master thesis I worked on Thermo-elastic Analysis of functionally graded sandwich plate based upon Reissner mixed variational theorem (RMVT).
