DAMPING PROPERTIES OF VISCOELASTIC MATERIALS UNDER BIAXIAL STRESS.
Abstract
The damping characteristics of a temperature independent viscoelastic material are determined under axial, shear, and several combinations of both axial and shear loadings. A method for measuring these properties is devised by considering a double lap joint specimen and measuring the area of the hysteresis loops which resulted from the cyclic loading of the specimen under axial, shear, and several combinations of both axial and shear conditions. The complex elastic and shear moduli and Poisson's ratio are presented as a function of the strain amplitude. The experimental results of the damping properties under biaxial stresses are found to be in good agreement with the theoretical analysis. (Author)
