The simulation predicts the flow field, rate of strain and apparent viscosity of the semisolid materials under transient and steady state conditions.
However, for successful implementation of the technique, proper knowledge on the properties of the semisolid materials under deformation is necessary.

Bamboo fiber reinforced resin matrix brake materials were selected as research object, dry and wet friction experiment was conducted on MM200 abrasion tester.
Wear and corrosion of friction materials is either accompanied by mechanical broken of wear debris, or due to the collapse of the patches.
Water cooling will reduce the adhesion transfer of the materials between the friction pairs, so the friction coefficient and wear rate is lower than dry friction[9].

In this paper, the basic principle, typical prototyping systems are introduced, and rapid prototyping methods such as selected laser sintering of powder material, fused deposition modeling of threadlike material and laminated object manufacturing are presented.
Selected sintering of powder material (also called Selected Laser Sintering, SLS) In this system, the prototyping material is powder like polymer, metal or the compound of ceramic and adhesive and so on.
When prototyping, a layer of powder material is spread on a workbench, and is heated to a temperature slightly lower than the melting point, and then laser beam scans the material according to the cross section profile, the material scanned is melt and bond together to shape, the material unscanned is still powder and supports the workpiece.
b. selected fused deposition of threadlike material (also called Fused Deposition Modeling, FDM) In this system, threadlike thermoplastic material is delivered to the nozzle by supply mechanism, the material is heated to fused state within the nozzle, and deposits on the workbench according to the cross section profile, then the material is cooled down rapidly and solidified.

Boron alloyed steels, especially 22MnB5, have been the point of focus for the materials choice in hot stamping.
This leads to the demand for stronger and more ductile materials like AHSS (Advanced High Strength Steels).
