Abstract: 
Functionally graded materials are advanced materials which are mainly made up of two or more compositions and generally an accurate pattern of the distribution of particles is not available. Therefore, the effective material properties of the composition such as Young’s modulus, thermal expansion coefficient, density, etc. can be evaluated by the volume fraction distribution and the approximate shape of dispersed phase. The advantage of using these materials mainly is that they can survive in high thermal gradient environments, while maintaining their structural integrity. However, FG materials are now developed for general use as structural elements in different engineering fields such as Nuclear engineering, optics, Biomaterials, refineries, power plants, etc. Also the applicability of these materials in some new filed of research such as energy harvesting has been examined recently by some researchers. Various material models have been developed to formulate the thermomechanical behavior of these materials and different numerical methods have been applied to solve the governing equations which have established for FGM structures during recent years. Based on the extensive applicability of these materials in engineering structures, numerous researches could be done in future on simulation, production and material property optimization of FGMs.
Biography: 
He got his B.S. in mechanical engineering in the field of Solid Mechanics from Shiraz university in 2001 (Shiraz, Iran). He received his degree in applied design in mechanical engineering from Iran university of science and technology in 2003 (Tehran, Iran). In continue, he pursued his education in Ph.D. in Solid Mechanics at shiraz university (2004-2009). He was assistance professor at Shiraz Azad University from 2009-2017. He has done different researches in the following areas: - Computational mechanics and simulation. - Functionally graded materials and composites. - Vibration and dynamic analysis - Fracture mechanics and life estimation. After Immigration to the United States in 2018, he has started a second Ph.D. in mechanical engineering at the University of North Denton and he is working on design, simulation and controlling of vibration suppression systems.
