摘要
The subject-matter of the invention is the method of measuring mechanical properties of materials, namely biological materials, when at least one parameter characterising the viscoelasticity of the material is detected; the method consists in attaching an inertial member to the measured sample of the viscoelastic material or to the probed put into contact with the sample of the viscoelastic material, the weight of the inertial member being substantially higher than the weight of the sample or probe, while the inertial member or probe are at least partially formed of ferromagnetic material; by means of a contactless sensor, impulse and/or transient characteristics in straining the sample in bending, tension, compression or torsion are measured. Another subject-matter of the invention is an apparatus for carrying out the method according to the invention, i.e. the inertial viscoelastometer. In an advantageous embodiment, the apparatus according to the invention is modified for determining viscoelasticity of materials in straining the sample in bending, tension or compression. Another advantageous embodiment enables to determine the viscoelasticity based on measuring the surface of the sample or to determine the viscoelasticity of a sample in the form of a membrane.
