Introduction Random packings of spheres have many reflections in materials science.
Real materials, such as oxides or sulfides, include at least two elements with atoms of two different sizes.
In spite of the great importance of the problem for materials engineering, only general algorithms have being proposed; they give satisfactory approximations in some selected cases.

Introduction Beginning as early as the 1990’s, high toughness engineering cement-based composite materials (ECC) were presided and designed by Victor.
And based on these, A variety of cement-based composite materials continue to spring up with high ductility and fine multiple cracking, such as ductile fiber reinforced cementitious composites, engineering cementitous composite, ultra-high toughness cementitious composite, and so on[3,4].

The interest of this approach is shown discussing its application to few examples of engineering interest (composite materials, masonry structures, bone tissue).
The design of properly engineered materials is a challenging issue from both technological and theoretical point of view.
On the other hand, reliable theoretical and numerical tool are needed to make accurate predictions on the properties of an engineered material.
In particular, it is well suited to deal with materials with rigid microstructure [14-16].
Such a description is well suited for materials like masonry and many short fiber composites.

Most geo-engineering cases have non-linearity.
Particularly, the material non-linearity is an important character of geo-engineering cases.
Step-loading is the typical case of geo-engineering.

Material Point Method in Impact Engineering Problems Chen Wei-dong 1,a ,Zhang Zhong1,b 1College of Astronautics and Civil Engineering,Harbin Engineering University,Harbin,China a chenweidong@hrbeu.edu.cn, b zhangzhong8866@163.com Keywords: impact dynamics; material point method; numerical Simulation; meshfree Abstract.The basic theory of material point method (MPM), which is a new meshfree method,was briefly introduced in this paper.MPM takes advantage of both Eurlerian and Lagrangian methods.
The key feature of the MPM is the use of the same set of nodal basis functions for both the mapping from material points to cell nodes,and the mapping from cell nodes to material points.
Thanks to the high pressure, materials show fluid characteristic.

Combining characteristics of pipe-jacking tunnel, this paper analyzed key-points of construction technology and engineering troubles which occurrence possibly in construction, and introduced some treatment measures.
There are kinds of materials of pipe jacking tunnel, such as steel pipe, ductile iron pipe, FRPM, vitified clay pipe, PVC pipe, asbestos cement pipe and concrete pipe.
Features of pipe jacking tunnel project Compared with ordinary civil engineering project, the pipe jacking tunnel has its own features as follows: The equipments are appropriative and the project is relying on the equipment.
So the risk of pipe jacking tunneling is higher than ordinary civil engineering project and demands the technicians to have the merits of being good at sum-up, mastering advanced technology and predicting possible troubles to avoid accidents and risks.
