Abstract
Accurate material properties are essential for the design of viscoelastic damping treatments and material properties are often the predominant error source process when modal strain energy techniques are implemented.
The trade-offs between various test techniques are discussed with primary emphasis on a system developed at CSA Engineering for direct complex stiffness measurements on viscoelastic materials. Issues such as analog front-end design, temperature control, and system software are discussed.
