Based on the approach to an automatic generation of homogenous properties of layers in graded material and microstructural models of materials, the programs are written by MATLAB.
The contact stress distribution curve will become smooth far from singular points in perfect homogenous materials.

Obviously, the new design concepts require new materials, and vice versa, new materials often require new, innovative forming processes and new tooling concepts, as well.
These contradictory requirements can be met by using higher strength materials.
From the side of materials science, the application of this design principle can be met by applying materials with high specific strength (UTS/r) and high specific stiffness (E/ r).

The experiment and simulation results indicated that this model could explain the drying process of grain materials well.
Experimental Materials and Method The corn, as a kind of typical grain materials, was the study object of drying simulation in this paper.
As said above, the grain materials included two kinds of different scale pore system at least.
The program generated the pore network physical model based on the structural parameter of grain materials.
