A review on modal characteristics of FGM structures

Abstract

Functionally graded materials (FGMs) are the advanced form of composite materials. They possess specific properties in unidirection or bidirection according to some mathematical models available in the literature. FGM structures are being explored in various engineering applications such as beam type structures are most commonly used in airplane propeller blades, robot arms, turbine vanes and astronomical erectable bangs etc. Plate type structures are particularly used in defense sector as penetration resilient resources for manufacturing of ammunition - resistant vests and armour plates. Shell type structures are used in manufacturing of load bearing components for aircrafts, ships, buildings and some parts of space launcher transport systems. This paper presents a broad discussion on vibration analysis of different types of structures i.e. beam, plate (circular, annular, rectangular, square, trapezoidal, skew) and shell (cylindrical, conical and spherical), which can be useful in the design of FGM modelling. This review paper is a collection of material based on vibration analysis of different FGM structures (beam, plate and shell) used in various advanced engineering fields. Further, this paper is categorized on the basis of modal behavior of FGM structures under with or without thermal effect.
