The objective of this proposal is to examine experimentally and                 numerically the inelastic effects in mixed-mode crack growths along             bimaterial interfaces.  Such crack growth dominates  adhesive failure           and fiber/matrix interfacial failure in a composite.  Specifically,             this study will lead to a better  understanding of the reliability of           adhesive joints and delamination failures of composite materials.               The lack of definitive experimental data has provided the excuse for            the theoreticians and numerical analysts to argue over the relative             merits of their models on the interfacial crack problem for the past            decade and half.  This study will provide the missing data and the              answers to the many theoretical conjectures. ***
