Summary

The universal appliance for measurement of basic rheological characteristics of solids and visco-elastic materials was developed and tested. The apparatus may be applied in biological, medical and pharmaceutical laboratories. The device enables measurement of the following parameters and characteristics: stress-strain curves in case of tension, shear, torsion and pressure load, breaking strengths, elastic modules, ductility and time dependencies of strain on stress (e. g. creep curves). The field of application involves measurements of mechanical characteristics of biological materials as skin, cartilage, vascular walls, bones, hairs, and other materials of similar parameters.
