Here the critical intensity of singular stress field is examined as the debonding criterion for all types of single lap joints under different adhesive thickness and overlap length. The intensity of singular stress can be evaluated by the application of the finite element method focusing on the stress value at the end element of the interface. It should be noted that except for the case of small overlap length the separation always occurs at the edge of the interface causing unstable growth and final brittle fracture. In this type of fracture it is found that the critical intensity of the stress singular field is constant independent of the adhesive thickness and overlap length., 13th International Conference on Fracture, June 16–21, 2013, Beijing, China}, pages = {813--816}, publisher = {International Congress on Fracture ( ICF )}, title = {Examination on a Criterion for a Debonding Fracture of Single Lap Joints from the Intensity of Singular Stress Field}, year = {2013}, yomi = {ノダ, ナオアキ and サノ, ヨシカズ} }
