Abstract

 The deformation behavior during the stretching of the steel / steel adhesive joint is investigated. The temporal evolution of deformation isopoles in the near-surface layers of sample compounds is revealed. A correlation is established between the stages on the deformation curves and the evolution patterns of the spatial structural elements, which on the surface of the steel lining reflect the spatially localized distribution of the deformation fields. These deformation fields are bounded by iso-lines, within which the deformation has the same meaning. It was revealed that on the surface of the steel lining, separation occurs into three types of areas: deformable areas of tension; deformable compression areas; nondeformed areas. At the stage prior to the destruction of the adhesive joint, a limit value of shear displacement was established, which is equal to 0.0067 mm. It has been shown that in areas close to the periphery in the areas of adhesion, stresses begin to grow in a direction perpendicular to the area of adhesion. These stresses contribute to the tearing effort. It has been established that in our case the nature of the destruction of the adhesive joint is adhesive.
