Abstract:
An integral part of the Damping and Metal Matrix for Precision Structures (DAMMPS) program involves the acquisition and dissemination of complex stiffness data for several viscoelastic material (VEM) specimens. Three such specimens have been tested by the Lockheed Missiles and Space Company, Inc. DAMMPS tearn: 3M Y-966, Soundcoat DYAD-606, and 3M ISD-112. These particular materials were chosen to demonstrate usable loss factor amplitudes which span the anticipated frequency and temperature range of operation for the structure studied under the contract. Future testing will characterize these and other selected specimens in more detail to provide an accurate material properties database for the detailed design task. Test data were collected very efficiently utilizing the Direct Complex Stiffness (DCS) method and manipulated/reduced using the VEMINT program. In this paper, salient aspects of the test and data reduction procedures are presented, as well as several forms of the complex modulus data.
