چکیده انگلیسی
A spectral finite element model for analysis of flexural-shear coupled wave propagation in delaminated, multilayer composite beams is presented. Concept of obtaining the exact spectral element dynamic stiffness matrix for delaminated beam is discussed. Computation is performed in the Fourier domain at FFT sampling points over broad frequency band. Post processing of the response is made in the time domain, which is suitable for structural diagnostics and broad-band wave propagation problems. Implemented numerical examples illustrate the influence of delamination on wave propagation in cantilever multilayer laminated composite beams.
