METHOD OF DETERMINING RHEOLOGICAL PARAMETERS OF LINEAR VISCOELASTIC MEDIA UNDER FOUR TYPES OF UNIFORM LOADING

摘要

Usage: study of mechanical properties of viscoelastic media, e.g. cheistobetonnyh. SUMMARY OF THE INVENTION: determination is carried out by removal of the two curves and creep detecting missing rheological parameters calculated. 20 yl. - shear loading, such as a simple shift in the instrument or device Tolstoho Weiler-Rebinder, followed by treatment with the experimental curves of creep of the material, allowing the guide to define a set of its rheological parameters. Known methods require four independent experiments on four different devices, which is a very time consuming process, especially if the required synchronization time for the experiments on the medium, the guide properties changed with time, for example during solidification. Furthermore, for some types of materials it is difficult or impossible to carry out certain types of uniform loading, for example; uniaxial loading of liquids, or full compression for vspuchivayuschihs media such as aerated concrete mixture.
