Commonly the fracture of the engineering materials used in micro cutting such as steel, 45 stainless steel, copper, aluminum and its alloys is often ductile fracture, the radius of cutting edge is from several microns to several microns in micro cutting, the size of grain in most of engineering materials is between 100 nm and 100 microns, the size of grain boundary is several micrometers, so tools is cutting in grain boundaries, the style of fracture is transgranular fracture.

A variety of tests have been performed to determine the actual characteristics and advantages of fibrous materials.
Quasi brittle materials like concrete have low tensile strength and strain capacity.

The surfacing materials placed upon the steel bridge decks would be specifically designed to provide enough stiffness and fatigue resistance to help reduce the high level strains in surfacing structure, but top-down fatigue cracking is still one of the major failure form in orthotropic steel deck pavements.
To further improve the gussasphalt deck pavement bending performance and life span, glass fiber grid material is introduced into the part between GA and upper layer asphalt mixture on the basis of grid composite material theory, to form Grid Reinforced Gussasphalt, whose advantages are analyzed in theory and verified by tests.

Introduction FRP materials with light weight, high strength, corrosion resistance, ease of construction and work with concrete good superior performances, is a new, efficient structural reinforcement materials.
So in order to make the fiber stress more direct and efficient, FRP materials should be pasted at ±45° direction on the core area.

This review covers diagrids with all the materials in practice namely concrete, steel and concrete-filled steel tube(CFST).
Mainly three materials are used for the construction of diagrids- steel, concrete and concrete-filled steel tube(CFST).
Different materials used for construction of diagrid structure are presented.
