  • Patent number: 4383450
    Abstract: There is described a measuring method for static and dynamic material characteristics in which to that material the above-defined characteristics of which are to be measured, there is applied by means of a force F, a constant predetermined deformation by compression or pressing-in and the deformation is retained for at least 10 seconds and preferably at least 15 seconds, whereby the building-up of force F from a moment zero which corresponds to that time where the force is applied, and the decrease thereof after said constant deformation has been reached, is measured as a function of the time, and the material characteristics are determined from suitable formulas.
