Abstract

The subject of rheology is the study of force-induced deformation and creep in materials, taking into account the effect of time too. The purpose of the measurements is to study time-dependent tension-deformation correlations, which include creep and tension-relaxation parameters, and viscosity. Due to the characteristic structure of biological materials, we try to introduce rheology through different materials. Our samples also include soft, semi-hard and hard materials from fish meat to human teeth. It is very clear from the obtained results that the internal structure of each material is influenced by many factors. These factors also interact with each other and they cannot be standardized in a single study.
