Abstract

Functionally Graded Materials (FGMs) are used in specialized industries, notably, in the aerospace industry, due to their unique response to thermal loads which are very prominent during spacecraft flights. The use of FGMs in the rapidly growing 3D printing area is also increasing interest in them, and proper modelling of FGMs is becoming a prominent development topic. This paper suggests a method of modelling FGMs using the ANSYS Workbench environment for dummy thermal loads in ANSYS Mechanical, which excludes the need for extensive FORTRAN programming typical of a significant part of FGM modelling methods. The method can be applied for complex geometries, imported from CAD software, works with shell elements bodies, and any distribution of materials throughout the FGM. Two case studies: one for 2D analysis and another for 3D shell elements analysis are developed. Two solutions are developed for each case: numerical solution, obtainable through the proposed method, and analytical solution. Solutions are compared, and the results yielded by the proposed method matched the analytical solution with high accuracy.
