The main goal of each laboratory stand is to stimulate a high intensity cavitation phenomenon and to evaluate the cavitation resistance of new structural materials.
The assessment of cavitation resistance of structural materials is also carried out on devices simulating the impact of microjet taking place in the final phase of the cavitational bubbles implosion.

It is based on reverse engineering technology, biomechanics and material mechanics.
As a result of the deformation, strain energy is stored in the brace material.
Otherwise, the brace material could be replaced by another with a different rigidity modulus.
Finally, such parameters as stiffness, size of brace and material modulus are confirmed.
