Abstract
The results of an analysis of the mechanical properties of an elastic adhesive in metal–ceramic adhesive joints under quasi-static low-cycle mechanical-shear loads are presented depending on the thermal and mechanical history of the samples. It is shown that the value of the maximum load in the load–strain diagram is not the only characteristic of the destruction of an adhesive joint. When this load is reached, the increase in deformation occurs without an increase in stress. It is assumed that, under this load, the formation of strands begins in the gluing. After a ten-cycle load, the Mullins–Patrikeev effect was not found in the studied samples.

Notes
In the case of metal, this is the beginning of neck formation [5]. For elastomers, this phenomenon was discovered for the first time and, apparently, is associated with the formation of strands in the adhesive.
