Method of Determining a Thermomechanical Diagram for Stressed Cylinder Connections upon Their Plane Deformation

In this paper, we propose a new method for determining the thermomechanical diagram (TMD) when testing stressed cylinder connections under plane deformation conditions. The application of the TMD method is based on the identity of the specification and restoration of deformation on the samples and in the implementation of shape memory by a force element in the structure. Therefore, such a problem statement is necessary for calculating the contact load when forming pipe connections by couplings with the shape memory effect.
