Abstract
The maximum value of the vibration decrement of a porous metal composite made using 3D technology is determined. The influence of porosity on the damping and stiffness properties of the composite is studied. The optimal porosity value is obtained, which provides a maximum of the vibration decrement at a significant load level on the sample. The results of numerical
calculation of the decrement for a composite made of chromium-nickel porous steel are presented.
