Creep test.
The three-element model of linear viscoelasticity is employed to evaluate the creep behavior of polymeric materials [6].
Materials Load (µµµµN) Max.
This means that these polymer materials have some nonlinear viscoelastic property in these indentation ranges.

Imported the existing model of milling cutter with fir-slot into Deform-3D.Before the simulation test, the tool material was set as M42, the workpiece material was set as Cr-Ni-Mo-V and the cutting parameters were set also.
As according to the source of cutting force, it is known that under the conditions of static cutting tool material, workpiece materials, basic cutting condition and rake angle, the only factor affects the cutting force is relief angle.
Saved the new model of the milling cutter into "STL" format and imported it into Deform-3D, then set parameters of cutting tool material, characteristics of workpiece materials and parameters of cutting (Table 1).

Abstract.
It is known that one of the simplest methods of forming surfaces with high tribomechanical properties is the electro-spark alloying (ESA) of metals and alloys with electrodes of various materials [1-5].
In this paper, we studied the tribomechanical properties of electro-spark coatings obtained with hard alloy electrodes and materials that synthesized carbides, intermetallic compounds, oxides, and other substances on steel C45 (St.
The main reason for the wear of materials is the adhesion setting of the contacting surfaces, accompanied by a scuffing and seizing of friction units.
The initial microhardness of the samples coated with different materials was determined on a PMT-3 microhardness tester.

Model:
Analysis of thermal environment required more strict conditions of the model than daylighting analysis; therefore, the enclosure of the space, materials of neighboring spaces and setting of switch of spatial heat area are all important.
The constructing material of Pufangtian was reinforced concrete; therefore, the model material was also reinforced concrete with few other materials for doors and window.
The specific materials used were listed in Table 1.
