Introduction The machining characteristics of engineering materials depend primarily on their mechanical and chemical properties.
Such properties depend on the machining process and the engineering materials used in production.
Therefore, cutting velocities should be limited by the fracture toughness of tool materials in high temperatures.

MRF in this aspect of the corresponding performance index is tested for the performance of the improvements of the corresponding reference data Sample treatment The volume density is 30% MRF, marking the magnetorheological materials for A; The volume density is 30% MRF, rested for a month or more, poured the upper silicone oil, the rest is stirred again, as a "sticky" shape material, marking the magnetorheological materials for B.
Figure 6 shows two different experiments, with the comparison of the two tests by different personnel with the same materials and the time the same instrument of two curves.

Flexural stiffness reduction factor of reinforced concrete columns with special shaped section considering characters of material nonlinearity and geometrical nonlinearity is lacking corresponding research.
As a result, a flexural stiffness reduction factor is proposed to consider characteristics of material nonlinearity and geometrical nonlinearity of reinforced concrete columns with equiaxial T shaped section.
