To explain the application of structural and thermal loads on FGM it is necessary to analyze the behavior of functionally graded materials (FGM) under application of the external loads as well as under the changes of temperature. Therefore, the application of the progressive change in material properties through the volume, as in FGMs, provides the comprehensive advantages in lots of engineering cognations. It is a realization that FGM structures can experience static characteristics like compression, tension, bending and torsion forces. Furthermore, warm loads are stated above as warming and cooling can also be used to highlight way of behaving of FGMs at specified temperature gradients. In another case, software packages such ASYS is used in applying numerical analysis as the various loads are applied on the FGM at the same time. The structural analysis employs use of finite element analysis (FEA) to estimate the stress and strain level in FGM and to estimate the temperature distribution of the material. This can also give FGMs variation in thermal and mechanical behavior across their volumes to enable them to achieve specific performances designed for specific uses. Through understanding the analysis results of FGM simulation, it is possible to recognize the behavior and trends of FGMs under different loading conditions, so that the theory-based improvement for FGM structure and designing, as well as the safety and stability assurance for FGM under practical application, can be provided. When FGMs are included in various designing practices, it is realized and understood that the practice is widely used in aviation designing, auto employing, and biomedical designing. Thus, the FEA is employed to determine the behavior of FGMs under applied external loads and temperatures during the process of applying structural and thermal loads to FGMs. The information attained helps to improve the design problems of FGMs and to guarantee safety and reliability in a real-world situation.
