抄録

The complex shear modulus of a thin adhesive layer may be determined from the torsional resonance test on a composite beam with metal facings and an adhesive core. In order to determine this shear modulus from such method ( Composite Beam Test Method), it is necessary to know the torsional rigidity of a three-layer composite beam. This was analyzed exactly, and a method to determine the complex shear modulus was presented herein using the result of analysis. An error analysis is essential in this method for reliable determination of characteristics of the extremely thin adhesive layer, and it was performed in the present paper. The test beam configuration which minimized the resultant error of the shear modulus were discussed theoretically based on the results of error analysis .Validity of the present method was verified by some torsional tests which were carried out on the symmetrical elastic beams bonded by two types of structural adhesives at several temperatures.
