I came across this effect on
http://www.rognerud.com/physics/ and it took me some time to widen my basic knowledge in electromagnetism, which proves to be quite tough for me, and still a lot of white spots left, but helped me to understand that I wasn't right thinking that tensile stresses are the reason for "antigravity" while in the same time the derived earlier result is right and can be used to solve this effect either (pic.1).

A - the surface area of the plate
d - distance between the plates
md - mass of the dielectric
mp - mass of the plates
V - voltage differential between the plates
e - permittivity of the dielectric
F - force between the plates
r - specific weight of dielectric

Looking at the two pictures again at the time I realize that probably the reason of this, is in the same deformation that will occur in both cases. Huk law, or in other words, if we strain a body in direction x it will reduce its size in y direction, and so compression in direction y will increase size in direction x (pic.2)
On the same web I reed another remarkable paper “Free Fall of Elementary Particles” by Nils Rognerud.
In consequence of that the following two pictures start to take shape (based on my elementary knowledge of atom structure at the moment).
The first, if we take planetary model of atom, (pic.3) leads me to the idea, that reduction of gravity is consequence of deformation of electron orbit, his eccentricity, and redistribution of electron velocity on different sections of the orbit due to electric field. Which on other side will lead to a new picture of divergent electromagnetic field around the atom and change in his dipole moment in different directions.

If that is right then it's naturally to suggest that gravity field is created by similar and opposite to this picture. In fact conditions for it doesn't lack. As we know in depth the pressure P increases, and in consequence of that we could expect some decrease of electron orbit radius and increase of its velocity. Also there is a gradient of pressure DP over the atom which will lead to additional deformation of orbit and redistribution of electron velocity (additional acceleration in lower half), further we could expect that the core (the proton) seeking new equilibrium state will shift up (pic.4 left). Because of the same boundary conditions in A,B,C,D for all elements such substance could behave similarly to Einstein-Bose condensate.

Well this is by now, I am still not 100% convinced whether the action of this two divergent magnetic fields (by movement of the electron and the proton) together with dipole moment change in different directions are the reason of force that we associate with gravity. Still not, for the fact that right solutions did not always lead to right conclusions (as I proved to myself) and my fragile knowledge in quantum mechanics and the following conclusion that follows directly from represented picture.
If for some reasons the pair proton-electron is destroyed, then the field (gravity) will no longer exist, which in cosmological scale means that not all existing mass in the universe will create gravity because such conditions do exist in all stars and bigger planets and could lead to considerable error in calculations of the mass of space objects
? Despite that, this picture increases my suspicions that gravity is more likely product of interaction between particles, rather natural characteristic (function of the mass).
Still many unclear things remain, I'll try in near future to learn more about quantum mechanics and check to what extend I'm right up to the moment. I'll not be surprised if solution already exist there in some kind of form because internal stresses and volume density are the problems that concern knowledge for a quite long time.
