Abstract
An exact analytical solution to the problem of the wave motion of a tubular semi-infinite rod interacting with its surrounding elastic medium according to the Coulomb’s law of dry friction under the action of an exponentially falling dynamic load on its end (modeling of explosive charge detonation) and in the case of a finite mass impact by a rigid body along this end is obtained. The pattern of wave motion depending on the loading parameters is investigated: the leading and trailing edges of the elastic wave are determined, and the distribution of residual strains as it passes along the rod is found. The obtained results can be used in calculating the deformation of oil and gas pipelines in the case of shock loads.
