Some Problems in the Measurement of Dynamic Modulus of Viscoelastic Model Materials

CODEN: JTEVAB

Abstract

Commonly used model materials in structural model testing are gypsum, added-weight emulsion, added-weight rubber, PlexiglasTM, epoxy resin, and polyvinyl chloride PVC. These materials are viscoelastic and their mechanical properties are unstable, especially the elastic dynamic modulus. To discuss the principle of variation on the elastic dynamic modulus, the materials PlexiglasTM, PVC plastic, and added-weight rubber were chosen for dynamic testing; the factors of temperature effect, size effect, and the effect of loading modes are also discussed.
