ELASTIC PROPERTIES OF MATERIALS of the UNDERGROUND PIPELINE
For the reliable transportation of liquid media, corrosion-resistant and strong pipes are required. Аn effective use of them for underground installation requires the determination of the VAT of the pipe taking into account the effects of temperature, soil, liquid media, and also on the basis of the material components. The composite material of which the pipes are made, belongs to a complex mechanical system. The main problem in solving problems of modeling the mechanical properties of a heterogeneous medium is to determine the conditions of the averaging procedure that is correct from the point of view of predicting the effective properties of an idealized medium on the basis of data on the mechanical properties and geometric characteristics of the components of the real medium. In this regard, the task of assessing the effect of elastic material properties on the VAT of an underground oil pipeline is of great practical importance and is relevant.
