Abstract:

Development of an optimum configuration for a specimen for use in obtaining the maximum shear strength and shear modulus of various adhesives is reported. A torsional shear specimen was adopted for optimization. It was made by bonding an adherend ring between 2 loading blocks. When the specimen is loaded it acts like a thin-walled cylinder in torsion. If the radius of the ad herend ring is large compared with the width of the ring, the shear stress is very nearly uniform and remains so until failure. A special test jig was built for testing this specimen. Investi gation of the usefulness of the double shear sheet specimen to provide a pure shear loading across a section of sheet material is discussed. Author
