Free and forced vibrations of cracked Euler–Bernoulli beams are analysed by the Haar wavelet method. Stiffness reduction for open V-shaped edge cracks is calculated. To demonstrate the efficiency of the proposed method, three problems about bending and vibration of cantilever beams are solved. The obtained results are compared with available data of other authors.
