Introduction Composite materials have become increasing application in industries such as aerospace, automotive, mechanical engineering, civil and chemical engineering.
The material is assumed to be initially free of damage such as technical cracks (size in the order of a mm) and delaminations but not free of tiny defects/flaws (size in the order of microns) prior to loading. 1.3 Failure Theory Modelling the behaviour of materials remains one of the most difficult challenges in engineering.
-Verification of engineering approaches, based on a qualified FEA-output level when analysing the test specimen, is necessary.
For 'higher textile pre-forms' (woven fabrics, 3D, heavily stitched laminates, etc.) engineering models have to be developed.

Prior to measurement, the catalyst materials were dispersed in ethanol, deposited onto 300 mesh carbon-coated grids, and subsequently dried.

Study on Rural Environment Problems and Countermeasures during China's acceleration of urbanization YANG Zaifu1,a YAO Chuenyun2,b XU Lianlian1 1School of Environmental Science and Engineering, Donghua University, P.R.China 2Songjiang Environmental Protection Bureau.
Shanghai Songjiang, P.R.China aemail: zzfyang@dhu.edu.cn, bemail: yaochunyun@s163.com Key words：acceleration of urbanization；Rural Environment；Countermeasure Abstract: Along with the rapid development of rural economy and the acceleration of urbanization, environmental pollution have gradually penetrated into China's rural areas and became more and more serious. the present situation of China's rural environment problems were analyzed and some effective countermeasures and suggestions for how to protect China's rural environment.
Although in Industrial Park which has an high-efficiency collected network, part of the businesses treat waste gas nonstandardly, they pay attention to "three wastes" producing from productive technology, ignore primary contamination from Materials and potions using in production process, such as stench odor of raw, pungent smell of chemical agent, running of the Saponification water, Causing significant environmental pollution.
(5) The total amount of main pollutant of industrial enterprise should be controlled within country's issued goals; the rate of sewerage collection of industrial clusters enterprise reached over 90%, key environmental protection supervision enterprise pollutants stable success rate keeps 95%; General industrial solid waste comprehensive utilization and disposal rate reached 95%, dangerous waste disposal rate was 100%

Symbiotic unit (U), symbiotic mode (M) and the symbiotic environment (E) compose three elements of symbiosis, in which the symbiotic unit is the basis of symbiotic environment conditions, and symbiotic mode is the key.
(3) Function internalized effect: To some extent, integration of the inner workings of the process of scenic area and urban area, for what, in some areas, such as material flow, knowledge flow, information flow and capital flow and other functions, external instability transactions converted to full internal or semi-internal circulation At the same time, the internal feedback system enables the growth of the symbiotic unit to get a higher quality guarantee in scenic area and urban area.
It control the nature of the construction land, intensity of use and the space environment, what plays a key role in the control of the rafting scenic town and city symbiosis.
When planning, the mandatory control indicators in scenic area medium-unit include land usage--volume rate Landscape Tour land, visit the facilities land the residents social land, transportation and engineering land -- measured by used block ,index is not Figure 8 Indicators control charts of symbiotic medium-unit more than 0.8; Building density -- measured by used block, the index is not greater than 20%; Green rate - measured by used block, the target of not less than 50%; Building height limit -- the index is not more than 24 meters; Architectural forms -- Lingnan or European architecture.
Through towns of primary and secondary roads, water systems, municipal facilities pipeline, it achieves exchange for the media about material, information and energy and promote the sustainable development of the scenic area and urban symbiosis. 4.

Dynamic Simulation for Driver-Tricycle-Road System with Rigid-flexible Coupling Xiang Han1,2 1College of Mechatronic Engineering, Xuzhou Institute of Technology, XuZhou, 221008, China 2College of Mechatronic Engineering, China University of Mining and Technology, Xuzhou, 221006, China E-mail:xnghan@126.com Keywords: Tricycle; Rigid-flexible Coupling; Dynamics; Driver-tricycle-road System Abstract.
The Establishment of the Tricycle Rigid-flexible Coupling System Dynamics Model To establish the tricycle rigid-flexible coupling system dynamics model efficiently, the author first constituted its multi-rigid-body dynamics model, then replaced corresponding parts rigid model with flexibilities of frame and leaf spring which are key role to the tricycle system performance.
The leaf spring is a elastic component of the suspension of automobile, engineering and agriculture transportation vehicle, which is used to transfer lengthways and transverse force.
The essence of BEAM is to divide every leaf spring into several small pieces that are seen as rigid body, but every two pieces are connected with mass-less BEAM flexible beam whose stiffness and damping matrix are calculated automatically by Adams according to the cross section and material parameters of the leaf spring.
