Biomechanical couple interactions

Micropolar continuous medium theory from the beginning was modeling theory. It predicted in that medium existing of mass angular momentum, asymmetrical stress forces, stress moments and mass force momentum. On the beginning there was no able to interpret angular momentum, stress moments and mass force momentum on physical matter known base. In 70’s of XX age there were provided an examples for ferromagnetic, paramagnetic and dielectric bodies. This paper gives attention to interpret those effects in biological structures. On example of human blood there is showed application of Langevin’s paramagnetism classical theory and its mechanical results. In the paper there are presented interesting examples of biological structures which had mechanical results using electric dipole moments.

In mechanics of continuous media, one of the sub areas is the coupled field theory describing interactions of mechanical, thermal, diffusion and electromagnetic field. All this physical fields are represented in the tensors introduced in this theory. Taking into consideration the momentum and angular momentum of the electromagnetic field in medium requires introduction of the fields: couple stress, mass angular momentum and mass couple in balance equations. From the vectorial nature of momentum, angular momentum, force and couple it appears that the stress tensor and couple stress tensor are the second order. Bearing in mind the importance for modern technology of the physical properties of the surface and surface layer of a solid, the conception of balance equations will be applied to describe the material surface interacting with an electromagnetic field.
