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].

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.

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.

Solving the problem of water is based on water Engineering,but talents is the key to the efficient operation.
The highest of urban flood risk are Tianjin, Wuhan and Guangzhou[5].Fourth, water supply and drainage engineering is the main application fields of new materials such as pipeline and membrane material.
New materials, new equipment, automatic control technology and information technology have been widely applied to water supply and drainage engineering, greatly promoting water supply and drainage technology innovation and changes in talents cultivating mode.
The CDIO engineering education model is gradually extended,there are two batch amounting to 38 universities in China, focusing on mainly mechanical engineering and electrical engineering.CDIO emphasizes on cultivating engineering capabilities, lack of paying attention to students' career development.
Figure 4 shows that water supply and drainage science and engineering curriculum system includes four aspects such as engineering foundation and introduction, engineering conceive and design, engineering implement, engineering operate.

Rock, joints and fissures in fault for cutting the geometry of the boundary, rock materials division as characteristics, automatically control the border of rock mass cutting, at the same time take the grid as the carrier, rock geometry and topological relationship attached with mechanical properties for geotechnical engineering, all kinds of numerical calculation method of grid generation provide the most basic common graphics data method.

These regulations had a great impact on the process of vehicles engineering design as they influence the materials used during the manufacturing process such as metals, additives or plastic and polymeric composites.
Plastic and polymeric composites such as polyacetal, polyphenylene ether or other engineering resins are a key part of the evolution of car industry.
Another advantage of using such materials is the safety of passengers.
This trait makes all polymeric materials bio resistant and persistent in the environment.
