“…The second task can be solved in an automated mode by calculating the function set in the software. At this stage, characteristics of the SSS are determined (Zenkov et al 2019). In accordance with the method described in (Zenkov & Tsvik, 2018;Zenkov, 2017;Tsvik, 2017), the third problem can be solved if there are laboratory specimens appropriate for mechanical testing.…”

A study of the stress-strain state (SSS) of disc specimens has been conducted when testing specimens with stress concentrators (grooves). The research has shown that the truncation of circular discs along two symmetrical chords makes it possible to change the type (the ratio of principal stresses) of SSS that occurs at the destruction site. Therefore, these specimens can be used to assess the structural strength of materials on standard single-drive testing machines, taking into account the real type of SSS that occurs in the bearing elements of machines. The results of numerical SSS modeling have been used to build the dependences of the SSS type and level on geometric parameters of specimens. Geometrical parameters can be chosen for a certain SSS type to assess both the static and fatigue strengths of materials used in the manufacture of bearing elements.

A description of laboratory unit and a finite-element mathematical model is given, the joint use of which makes it possible to carry out studies of the stress-strain state of flexible hoses based on plasticized PVC with spiral reinforcement made from rigid PVC. The results of laboratory tests and numerical modeling of PVC hoses during freezing and heating to various temperatures are presented. The result of the study is the determination of the modulus of elasticity of the PVC hose base material depending on temperature.
