METHOD AND APPARATUS FOR DETERMINING STATIC AND DYNAMIC CHARACTERISTICS OF VISCO-ELASTIC MATERIAL

摘要

The invention relates to a method and apparatus for determining the characteristics of a viscoelastic material. BR/ With the aid of a force F, a predetermined constant strain is applied to this material by compression or printing, and the establishment of the force F is measured from a zero momentum and its decrease after that the constant strain has been reached, as a function of time, and the characteristics of the material are determined on the basis of a series of formulas into which the measured force is introduced, the apparatus comprising a pressure body 2 fixed together with a force sensor 4 to a movable element 5, detection means being provided for the commissioning of the force sensor during the displacement of the aforementioned element 5.
