Abstract:

Experience in the commercial design and manufacture of adhesive joints has indicated that the most severe condition for adhesive joint fracture is the cleavage or pure mode-I condition. This commercial practice experience has been verified by the relatively small amount of well characterized fracture mechanics FM test data on pure mode-I and mixed mode adhesive specimens. In fact, the lack of evidence for a degrading effect of shear loading is one of the most compelling reasons that more effort was not expended on mixed-mode adhesive FM methodology in the earlier studies. A second reason was that development of suitable mixed-mode specimens is considerably more difficult than has been the case for pure mode-I loading. Author
