With the increasing use of composites, plastics and thin sheet aluminium in industry, design engineers are relying more on adhesives as a method of joining components. Although the stresses and strains within an adhesive joint can be predicted with accuracy using closed form, semi-closed form or numerical methods, little success has been achieved in determining a failure criteria applicable to all joint configurations and modes of loading. At best the present failure criteria give an idea of the failure load within the tight constraints of closely specified loading and joint geometry.
