Testing Structural Adhesives for Properties Necessary for Stress Analysis
Stress analysis of a bonded joint produces the information needed to predict the service performance of the bond. To achieve this, two sets of test data are needed: (1) the adhesive properties necessary to calculate the adhesive stress in the joint; (2) test data from bonded specimens which provide the allowable stresses on the adhesive. “Allowable” means stresses that must not be exceeded in service. With these two sets of data in hand, the analyst compares the calculated stress to the allowable stress in order to predict the performance of the adhesive in service.
