This work reports a modelling method of functionally graded materials (FGM) using ANSYS APDL. ANSYS, as many other analysis software packages, does not provide a direct way to model variation in material properties as a function of position. However, ANSYS offers the option of temperature dependent properties; and ANSYS also offers the ability of assigning temperature values according to the position; joining these two abilities offered by ANSYS, the material properties would be position dependent. In this work, using ANSYS APDL, dummy thermal loads are used to obtain FGM distributed properties. The presented modelling method is explained and then applied to some case study of static analysis to verify its accuracy by comparing its results with the analytical solution from the case study source. The main advantage of such a method is its simplicity and ease; it does not require deep knowledge of mathematical models of FGM and delivers high accuracy. Although in this study ANSYS APDL is used, one can apply it in ANSYS Workbench Mechanical or any other analysis package that has coupling capabilities of structural and thermal studies. The presented method is already mentioned in the literature, but no single documentation about it is found. This paper presents a complete representation of the method.
