EVALUATION OF THE COEFFICIENT OF TRANSVERSE DEFORMATION AT THE AXIAL-SYMMETRIC DEFORMATION OF CONTINUOUS MEDIUM

Abstract

The article is devoted to the question of theoretical estimation of the value of the coefficient of transverse deformation in continuous medium under the conditions of axial-symmetric deformation. It is shown that the value of the coefficient of transverse strain essentially depends both on the mechanical characteristics of the material of the half-space, the level of development of the stress-strain state at considering point, and on the type of the mathematical model of the continuous medium (geometrically linear or geometrically nonlinear) and may exceed the limit value for linear- elastic body, equal to 0,5.
