Many engineering problems can be solved using a linear approximation. In the Finite Element Analysis (FEA) the set of equations, describing the structural behaviour is then linear K d = F (1.1) In this matrix equation, K is the stiffness matrix of the structure, d is the nodal displacements vector and F is the external nodal force vector. Characteristics of linear problems is that the displacements are proportional to the loads, the stiffness of the structure is independent on the value of the load level. Though behaviour of real structures is nonlinear, e.g. displacements are not...

Successful vibration analysis of continuous structural elements and systems requires a knowledge of material mechanics, structural mechanics, ordinary and partial differential equations, matrix methods, variation calculus, and integral equations. Fortunately, leading author has created Vibration of Continuous Systems, a new book that provides engineers, researchers and students with everything they need to know about numerical methods of vibration analysis of continuous structural systems.

This book introduces a new method for active vibration control of FRP rotating shaft. In the direction of composite rotor shaft system few works are also available. The use of composite material is increasing day by day in the various industries because of FRP composites are lighter, more durable and have infinite design flexibility. So details study of laminated composite shaft is required. Due to its light weight and flexibility this types of shafts do not sustains large vibration in the operational condition. Active vibration control of rotating composite shaft is also very important in...
