Abstract: The unsteady problem of the detachment of a beam glued to a rigid plate by an applied load is considered. The Euler beam model is used. Crack propagation is described by the energy balance equation.

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