Abstract: A mathematical model of vibrations of a beam with one fixed and another free end has been developed, taking into account the effect of dynamic hysteresis, which is described using fractional integro-differentiation. The solution of the model equation is found in analytical form. The use of the fractional integro-differentiation makes it possible to correctly describe the dissipative nature of the beam vibrations.

Keywords: mathematical modeling, fractional integro-differentiation, initial boundary value problem, elastic beam.
