The choice of theory for adhesive layer effort

Godzimirski J., Rośkowicz M., Tkaczuk S.

Vol. 19, No. 1

128-138

In the paper, the problems of adhesive layer effort was considered. The experimental tests of adhesives bonds were conducted in order to determine breaking loads. A technique a finite element mesh of adhesive layer subjected to shearing was proposed. Next the numerical calculations were conducted in order to determine distribution of stresses in adhesive layers at breaking loads. The components of stress tensor were used for the analytical calculations of reduced stresses according to seven hypotheses. It was found out that the maximal principal positive stresses hypothesis, the maximum principal strain hypothesis and the strain energy hypothesis make possible to estimate the adhesive layer effort with similar accuracy. Shape and the dimensions of the steel (S355J2G3) single lap specimen, the compression curves for Araldite AW 136H, the maximal principal stress values in the most loaded element of the adhesive layer depending on the elements' dimensions, modelling versions of the tree-layer adhesive layer's edges, distribution of the maximal principal stresses along edge section, comparison of the maximal principal stress distribution along adhesive layer's length, the stress-strain curve for Belzona 1111 adhesive and for Epidian57/Z1 adhesive, distribution of maximum principal stresses in adhesive layer of single lap bond subjected to shearing, are presented in the paper.
