THE PENINSULA BLISTER TEST - A HIGH AND CONSTANT STRAIN-ENERGY RELEASE RATE FRACTURE SPECIMEN FOR ADHESIVES

An extension of the island blister developed by Allen and Senturia to a peninsula-like geometry produces a fracture test which retains the very high strain energy release rates which are possible with the island blister, and also results in a constant strain energy release rate test for adhesive bonds. Analytical solutions are provided for predicting the strain energy release rates for this peninsula blister specimen when the blister adherend may be considered a plate, a pre-stressed membrane, and a simple membrane. Preliminary experimental results for a PSA tape are also presented. The analytical results suggest that the specimen may be extended to a variety of practical adhesive systems. © 1991, Taylor & Francis Group, LLC. All rights reserved.
