Introduction Composite materials are widely used in structures wherever light weight and high strength are the primary design drivers [1].
Operating environment plays a major role in the performance parameters of structures made of composite materials.

One of the most suitable applications for this technology is the manufacturing of a polymetallic functionally-graded material with a smooth gradient structure between two materials [17-20].
One of the most reasonable materials for obtaining bimetallic functionally graded materials for the electrotechnical industry and tribocouplings are materials based on aluminum and copper alloys.

Hidden flows and indirect flows Hidden flows are the quantity of the materials which “participate in” the economic activity but not be used, they are not into the process of metabolism but they must be invested into .such as the topsoil and overburden during the process of coal mining, this kind of materials are not into the metabolic process ad consumed by metabolic subject, we called them Hidden flow or Eco-Rucksack.

In ductile materials (like aluminium alloy), subjected to appropriate loading conditions, voids will form in the material, grow, then coalesce, leading to crack formation and potentially, failure.
Gurson studied microscopic voids in materials and derived a set of modified constitutive equations for elasto-plastic materials.

In recent years, ultraprecision grinding was researched as a new method used for hard and brittle materials, and the key here is how to realize material removing mostly by ultra-micro cutting and ductile shearing action.
Consequently, for ultraprecision grinding of hard and brittle materials, it’s difficult to identify material removal modes and define surface generating mechanism.
Plastic shearing mechanism of hard and brittle materials in ultraprecision grinding In 1987, a notable hypothesis was putted forward by American scholar T.G.
