Dynamic Characteristic Analysis of Functionally Graded Beams

The basic goal of dynamic analysis of simple structures is to forecast how a structure will respond to external excitation. One of the most crucial elements in engineering design is the material choice. Advanced composites known as functionally graded materials (FGM) is idealized using the power law to account for the continuously varying characteristics from one surface to another. The present study provides a detailed dynamic characteristic analysis of functionally graded beams (FGB) employing a unique finite element approach. A convergence analysis is conducted for the first six natural frequencies. Dynamic characteristics such as mode shapes and frequency response functions (FRF) for varying boundary conditions are reported.
