Dynamic modeling and simulation are preconditions and foundation to identify cracks in structures quantitatively.To establish an efficient and accurate dynamic identification model of cracked wedge beams,a high-order finite method is presented.The shifted orthogonal Legendre polynomials are taken as additional high-order shape functions for the transverse displacement field of a wedge beam element and the corresponding stiffness and mass matrices are derived in analytical form.The stiffness equation of the ...
