Abstract: Unsteady crack propagation is studied in the beam approximation. The Euler and Timoshenko models of beam theory are used. Crack propagation is described using an energy balance equation.

Keywords: elastic beam, Euler beam, Timoshenko beam, energetic criterion of crack growth, surface energy density, normal mode method, Runge–Kutta method.
