In this study, the tensile and bending tests were carried out to examine the strength characteristics of elastic adhesive joint for acrylic material with different adhesive layer thickness. At first, the failure stress of tensile test was compared with that of bending test. While the failure stress depends on the adhesive thickness for both tests, there was found an obvious difference in the failure stress between above two tests. However, the difference becomes small if the mean stress on tensile site is used in bending test. Besides, maximum energy density of bending test coincides with that of tensile test if it is defined at final separation. The optical examination upon failure surface shows that the tensile site of bending test is occupied by damage zone around many small bubbles. It was found that the tensile and bending strength characteristics of adhesive joint are common in several points.
