Edge Internal Stresses in Adhesive-Bonded Joints

4 Edge internal stresses in adhesive-bonded joints [Pg.251]

The determination of edge stresses in adhesive-bonded joints is based on their property of counteracting the bonding forces between the adhesive and the substrate— in other words, of decreasing the adhesion strength. [Pg.251]

The pin-shaped specimens used to determine edge stresses are shown in Fig. 4.7. They consist of substrates 1 and 3, adhesive layer 2, and pin 4 lapped to a conical hole in the substrate 3. An axial force P or a torsion moment Medge that cause normal and tangential failme stresses can be applied to the pin. The internal stresses, the pattern of [Pg.251]

As Fig. 4.7 displays, the concentration of stresses on the edges of the adhesive-bonded joint in this case reached 1.12, although a comparatively elastic adhesive was used. For the adhesive based on the PN 609-21-RK polyester resin, the overstresses on the edges exceed 2.1 for epoxy adhesives they are 2-10. [Pg.252]

This method for studying the edge internal stresses can be used for coatings as well, but in this case there is no second substrate. [Pg.252]
