A state vector solution to thick laminated circular plate of piezoelectric,piezomagneto and elastic media

The methodology is based on a state space formulation where a particular collection of elastic,electric and magnetic variables are used to determine the behavior of a layered transversely isotropic subjected to piezoelectric,piezomagnetic and elastic media under arbitrary loading conditions.The state vector equation of transversely isotropic space for thick laminated circular plate of piezoelectric,piezomagnetic and elastic media is established.By the use of the Hankel integral transform in finity the state vector equations are transformed into a set of ordinary differential equations.According to the theory of ordinary differential equation and the Caylay-Hamilton theorem,the solutions of state vector equation are obtained which are the product of initial state variables and transfer matrix.The general formulation of the solution for thick laminated circular plate of piezoelectric,peizomagnetic and elastic media is given using the method of transfer matrix.
