The Pure Bending Task in Case of Composite Rod Based on Four-Element Model

In the presented paper is stated distribution of deformations and stresses development at external constant force moment in the rod with taking into account geometric characteristic as well as the time factor based on the four-element model. The values of the curvature and rotation angle are estimated. The values of deflection of rod with dependence on its coordinate and time are determined. The behavior and distribution of arisen in the cross-section of rod stresses at constant deformation (the case of relaxation) depended on the time is also determined
