Abstract
The elastic finite element analysis (FEA) and the experimental method of testing the
cleavage strength of the joint were used to investigate the effect of the recessing as well as its length
on the stress distribution in both the mid-bondline and the adherend near the interface along the
bondline of adhesively bonded steel cleavage joint. The results from the FEA simulation showed
that the peak values of the stresses distributed in the mid-bondline were nearly the same when the
length of the arranged recessing was not greater than 10 mm except that the shear stress Sxy was
increased a little when the length of the recessing was increased. For the normal stress Sy near the
interface of the joint with a 16 mm length recessing, the peak stress in the adherend is about 49%
higher than the one in the adhesive at the left edge of the joint. And it is supported with the results
from the experiments that the ultimate load of the steel-to-steel cleavage joint decreased a little
when the gap length was less than 10 mm.
