A Triangular Double Cantilever Beam Test for Measuring Adhesive or Cohesive Fracture Energy

reportActive / Technical Report | Accession Number: ADA243151 | Open PDF

Abstract:

A thin layer of adhesive bonded between two stiff elastic plates of uniform thickness and triangular in shape is recommended as a test specimen for measuring cohesive or adhesive strength. It has marked advantages in comparison with current ASTM tests in simplicity of construction and use. Examples are given using silicone rubber layers bonded between steel plates. Double Cantilever Beam DCB tests have been widely used to measure the strength of stiff structural adhesives because the experiments are simple to perform and analyse.
