Damping in metal-matrix composites. Theory and experiment Conference Paper

In order to measure intrinsic material damping one must use a uniform strain field. A new method for measuring damping in uniaxial loading is presented. The phase by which the stress leads the strain is determined to an accuracy of 10-4 radians using the elementary theory of Fourier transforms. The technique is then used to study the laminate. Following Ni and Adams [1], a model for calculating axial damping is presented. Close agreement between theory and experiment is observed.
