| contents | The transient response of sandwich and laminated composite structures with viscoelastic layers under impulse loading is studied using the finite element method. On this reason, the finite element models of sandwich and laminated composite beams and plates have been developed. The viscoelastic material behavior is represented by the complex modulus model. An efficient method using fast Fourier transform has been proposed. This method is based on the trigonometrical representation of the input signals and matrix of the transfer functions. The present implementation gives the possibility to preserve exactly the frequency dependence of the storage and loss moduli of viscoelastic materials. Numerical examples are given to demonstrate the application and validity of the approach presented. |
