Introduction The qualities of concrete like wide applicability, the abundance of raw materials, decent fire resistance, economical and ease of use, makes it the most widely used construction material in the world [1, 2].
This postulate is called the Irwin criterion for fracture of brittle materials.

Experimental design The polymer modified cement concrete (abbreviated as PMC) is composed of cementing materials including polymer and cement.
Taking this into consideration, first we select host materials and modified materials composing PMC to try mixing traces of samples and then screen among them.

The composite material of foam aluminum-polyurethane is a kind of high efficient and economical composite materials.
Therefore a lot of manpower, materials and money will be saved by computer simulation technology.
When the impact energy was much high, the stress was cumulated at the bottom of composite material, a large scope of bending deformation was occurred on composite materials.

Through analysis and research on the surface topography of reinforced copper matrix composite materials, taking advantage of fractal statistical method to discuss distribution law about characteristics parameter which symbolizes the asperity, combining Monte-Carlo method with fractal theory to set up mathematics model of characteristics parameter which symbolizes size of asperity , talking about the construction of iterated function system in fractal interpolated theory, a easy realizable friction materials surface topography simulation algorithm was put forward.
Let friction material plane is a square with bound length L, noting and as maximum diameter and minimum diameter respectively, and is number of asperity.
In conclusion, friction material surface topography simulation map was given in figure 1.
