A Specimen Configuration for Testing Adhesives in Fatigue and Creep

A SPECIMEN CONFIGURATION FOR TESTING ADHESIVES IN FATIGUE AND CREEP [Pg.301]

The need is to develop a test to produce adhesive fatigue properties which are useful to the designer. We consider that the skin-doubler specimen has this potential. It combines the capability of stress analysis with a failure mode faithful to that of the actual structure (see Ref. 4). The results will reflect the strength (durability) of the attachment in terms of stress (load) in the skin. [Pg.301]

The goal is to fail the adhesive, not the metal, in fatigue. This may well be impossible at ambient conditions for many adhesives and reasonable metal gauges. On the other hand, testing in hostile environment increases the probability of adhesive failure rather than adherend failure. [Pg.302]
