AB  - A wavelet finite element method (WFEM) is developed to analyze the dispersion relation for one-dimensional phononic crystals (1DPCs). In order to calculate the band gaps (BGs) of 1DPCs, the wavelet finite element model is constructed using a slender beam element based on B-spline wavelet on the interval (BSWI). Combining with the Bloch-Floquet theorem and <i>ω(k)</i> technique, the model will be simplified as a simple eigenproblem. The performance of the proposed method has been numerically verified by one numerical example.
