Abstract

The paper presents the results of studying the fracture of an epoxy layer in modified Brazil-nut-sandwich specimens. The effect of the angle α between the compression direction and the plane of the epoxy-metal interface on the fracture pattern is studied. The specimens with three adhesive compositions synthesized on the basis of the ED-20 epoxy resin are tested. It has been found that the cohesive failure mechanism dominates only at the angle α = 0° for all the epoxy compositions. The failure mechanism changes to the mixed adhesive-cohesive one as the angle α increased.

期刊介绍： Russian Physics Journal covers the broad spectrum of specialized research in applied physics, with emphasis on work with practical applications in solid-state physics, optics, and magnetism. Particularly interesting results are reported in connection with: electroluminescence and crystal phospors; semiconductors; phase transformations in solids; superconductivity; properties of thin films; and magnetomechanical phenomena.
