Abstract

We review some of our recent studies on elastic constants, internal friction, and related properties of two-phase materials. The occluded-phase geometry includes particles, short fibers, long fibers, and laminae. We review our measurement methods, which range in frequency from near-static to magahertz. Briefly, we review our theoreticl models, which include Mori-Tanaka effective-field, Datta-Ledbetter scattered-plane-wave ensemble-average, and Dunn-Ledbetter mechanical-concentration-factor extended Hori-Nemat-Nasser. Example materials include ceramic, metal, and polymer matrices. We show results for five composites: A1₂O₃/ZrO₂ particle mixtures, voids in sintered titanium, graphite fibers in a magnesium matrix, short SiC fibers in an aluminum matrix, a laminate comprising aramid-fiber-epoxy and aluminum layers.
