Stability of the Cylindrical Cover with the Elastic-Viscous-Plastic Filler at Axial Compression

Authors: Gotsev D. V.

Within the limits of the exact three-dimensional equations of stability of an equilibrium state of a cylindrical cover with a filler is investigated at axial compression. Calculations were spent for a case when the cover material was modelled by an elastic body, and a filler material – environment with difficult rheological properties – elasticviscous-plastic. The estimation of influence on size of critical pressure of parameters of a cover and a filler is given.

The Problem of a Longitudinal Crack with a Filler in a Strip

Authors: Antonenko N. N.

The method of the solution the problem of the central longitudinal crack with a filler in a strip is proposed. It is assumed that the jumps of the components of displacement vector is proportional to the corresponding stresses at its upper edge. Fourier’s method of integral transformation is used. The problem is reduced to a system of integro-differential equations. The effects of influence of thickness, mechanical properties of a strip and a filler of the crack on Mode I and Mode II stresses intensity factors (SIFs) are examined.
