EN 31 hardened steel with a hardness value of 63 HRc is used as a counter face disc material in the Pin-on Disc machine.
Later, after this critical temperature the oxide layer is not able keep itself adhered to the bulk of the material due to the softening of the material, hence the WR increases.

As paper material gets more expensive, structural optimum design of the honeycomb paperboard will become more and more important.
These honeycomb paperboards were composed with the same materials that are Kraft paper (350 g/m2) used as printed sheets and corrugating medium (110 g/m2) used as core paper.
These materials’ mechanical parameters [6] were as shown in Table 1.

The ROAV of compounds calculated as follows: ROAVi = 100 × OAVi/OAVmax(max representatives of the greatest contribution of overall odor material) and define: ROAVmax = 100 (3) By (1), (2) and (3)，ROAVi ≈ 100 × Cri/Crmax × Tmax/Ti (4) Apparently, all components are satisfied 0 < ROAV ≤ 100; and the larger the value, the more contributions to the odor of food.

In both cases, total volume of the material was held constant.
Otherwise, the elasticity modules of materials have to be taken into account and the formula has to be transformed into γi=(Est·Ist,i)/(Esk·Ist,i).

PHBV extensive application is limited because of high cost and certain inferior material properties such as brittleness and low impact resistance [2].
Materials; PHBV under the trade name Y1000P was purchased in powder from Ningbo Tianan Biologic Material Co.
The sample materials exhibited a shear-thinning behavior of the materials due to molecular alignment and disentanglement of the long polymer chains under shear deformation.
Because of stress relaxation in PHBV molecular chains, all the materials showed an increasing percentage of extrudate swell with increasing shear rate [15].
