“…Therefore, in the given case, after finding the solution of the problem in the elastic statement, using expressions (3.6) and (3.7) we can determine stress with regard to hereditary properties of the sealer. Abbasov and Rustamova (2015) solved problem in the elastic statement using the methods of elasticity (Amenzadeh, 1976;Lavandelis, 1976). The solution of the problem was performed in two stages in the elastic statement.…”

The stress-strain state of a sealing element in the form of a hollow cylinder is defined with regard to viscous-elastic properties of its material. Based on linear laws of heredity, an analytical formula allowing one to determine the axial load necessary for tightness of the surface of the sealing element and the cylinder wall depending on its physic-mechanical properties and geometrical dimensions is found. Influence of viscous-elastic properties of the material of the sealing element on its sealing ability is realized based on the hypothesis of elastic analogy. The results of numerical calculations are represented in the form of graphs of the external force necessary for achieving sightless. It is shown that viscous-elastic properties of the sealer material greatly influence its sealing ability. Because of heredity of the sealer material, values of the external forces drop in some cases by about five times.

“…A major problem with these studies arises from the ignoring influence of edge effects and heredity and also, mechanism of achieving tightness was not studied enough. The mechanism of achieving tightness was touched upon in the works [1] [2] [3]. As the experience of using sealing elements shows, the edge effects and heredity have a significant influence on their sealing ability [10] [11] [12] [13].…”

Character of contract pressure distribution between the outside surface of the sealing material and rigid cylinder wall depending on geometrical sizes and mechanical properties of a sealer under its unilateral compression, is defined. The magnitude of the axial load for achieving tightness is determined. The dependence between the magnitude of the axial load necessary for achieving tightness and geometrical sizes is determined. It is shown that with a decrease in the height of the sealing element, the axial load necessary for achieving tightness greatly increases. Threshold height of the sealer, above which contact pressure depends little on the magnitude of the axial load, is defined. The stress-strain state of the sealing element is defined with regard to viscous-elastic properties of its material. It is shown that this greatly influences its sealing ability.
