ABSTRACT

Material selection is one of the key points in the optimization of design process. Main challenge is, when the component is in hazardous working conditions. Pure metals hardly find any applications in present days because of the requirement of varying properties in both hardness and ductility. Over the years; metal matrix composites (MMC) have been developed to meet the functional requirement. Due to the varying properties of the MMCs they are allowed to use in wide variety of applications with changed or controlled volume fraction in the reinforcement phase. A low to moderate toughness of conventional MMCs is the main disadvantageous to some of the applications in which additional requirement of high-wear resistance and toughness. The need for a different property at various locations within a single engineering component is becoming greater as advancement of technology. This leads to the development of functionally graded materials (FGM).

In this work, an attempt is made to investigate the material behavior considering different basic geometries under fluctuating loads. The wind 260pressure acting on vehicle surface from starting to steady state speed of the vehicle on the straight road is taken as dynamic loads for different geometries. Transient structural analysis using finite element method is carried out with ANSYS Workbench 14.0 software. Five-layered FGM with titanium (Ti) as the metal and ZrO2 as the ceramic are used for the analysis. Engineering properties such as stresses, strains, strain energy and deformations in structural problems are evaluated for FGMs with three different domains. Comparative graphs were developed for different properties.
