Paper Abstract

The design and modeling of a bar made of functionally graded materials are studied in this paper. The material properties of the bar are harmonically varied along the bar. The bar is mathematically modeled and its governing equation is derived. The mode shapes and the natural frequencies of the system are calculated analytically using the boundary conditions at the two ends of the bar. The wave propagation in the bar is studied and the frequency band gap of the system is found. It is shown that by varying the material properties of the bar, we can design a system with a desired frequency band gap.
