Abstract : In order to approach idealizedconditions a torsional shear load is applied to the adhesive or braze through a circular specimen which produces a peripherally uniform shear stress with linear radial variations. The maximum shear strength of the adhesive. By measuring the adhesive strain as a function of load, stress-strain curves are obtained. The shear modulus of elasticity can be calculated from the stress-strain curve (adhesive must approach the requirements of a Hookian solid). Stress-strain curves have been obtained for three different types of adhesives. Reproducible results were obtained from the adhesive torsional shear apparatus using several sets of specimens bonded with the same adhesive. (Author)
