Life cycle engineering is the engineering and design of products and processes to minimize the cost and environmental impact for the life cycle phases of a product.
Material extraction is the process of retrieving valuable materials from layers of the earth’s crust.
Separation into material fractions increases the value of the materials recycled by removing material contaminants, hazardous materials, or high value components.
The shredded material is separated using methods based on magnetic, density or other properties of the materials.

Expression of Technological Aesthetics on Contemporary Western Landscape Materials Bing Chang 1,a, Songfu Liu 2,b 1Ph.D. candidate in School of Architecture, Harbin Institute of Technology Lecturer School of Civil Engineering, Northeast Forestry University，China 2Professor&Ph.D. supervisor in School of Architecture, Harbin Institute of Technology，China achangbing7731@163.com, bliusongfu2002@yahoo.com.cn Keywords: Contemporary Western, Landscape Material, Technological Aesthetics Abstract.
Material Form For a long time, the choice of landscape materials is to meet the local conditions and to meet the properties of materials.
With widely use of highly reflective materials, landscape material no longer reveals physical color of the material only.
Materials like glass can reflect the colors of surrounding environment.
In the expression of contemporary landscape works, the expression of material’s natural attribute is one of the key points.

Rough Entropy Model on Damage Assessment of Component-based Military Engineering Hui Yuan, Fengshan Wang and Houqing Lu Engineering Institute of Corps of Engineerings, PLA University of Science and Technology, China E-mail: WFS919@TOM.COM Keywords: Component Unit; Military Engineering; Damage Analysis; Rough Entropy; Military Simulation Abstract: To reason and reflect the mapping relation between physics damage and structure functions of military engineering, mechanism was established for damage assessment of component-based military engineering.
Especially focused on the overall function, the damage assessment of military engineering possessed the wide non-linear mechanisms, showing the typical complex characteristics about material, energy and information [1], which must reason the system damage from the overall functional vulnerability [2].
According to the structural characteristics of military engineering, and the component-based design idea of software engineering, damage assessment mechanism of component-based military engineering was established, as shown in Fig.1.
Through the searching process about the physical logic of the component units, physical damage parameters was reasoned, and then reasoning the system functions’ damage value of military engineering, which adapted to the special mechanism about the complexity of system structure, the diversity of system function and the non-linear perspective of damage key. 4.Rough Entropy Model on Damage Assessments Mathematical Problems of Damage Assessment for Component-based Military Engineering.

One possible approach for this is the use of different metallic materials in composite construction.
Especially in the transportation sector but also in general engineering the reduction of moving masses and weight and, at the same time, the increase of safety parameters are the key factors for future economic success.
One possible approach for this is the use of different metallic materials or metals and polymers in composite construction.
The work hardening of the materials is determined by uniaxial tension tests and quasistatic material models are used for extrapolation of the flow curves.
