Accelerated test method for water resistance of adhesive joints by interfacial cutting of open-faced specimens

Conventional test methods to evaluate the water resistance of adhesive joints are time-consuming. To reduce experimental time, open-faced specimens have been proposed. Numerical analysis indicated that the water absorption of an open-faced specimen was 3000 times faster than that of a conventional closed specimen. The strength of the interface between the adhesive and the adherend of the open-faced specimen was measured using the interfacial...
