The Iron Bridge demonstrated the application of cast iron as a new material for bridges and the use of cast iron then spread around the world.
The material properties and the sectional properties of the bridge members are listed in Tables 1 and 2 respectively.
They found that based on visual observations of the material and construction of the structure, finite element analysis with reasonable material property data can give good predictions of the actual behaviour of masonry arch bridges.

Their anti-oxidant, anti-reversion capability, high-temperature strengths and creep performance are better than most of metallic materials,furthermore, their plasticity is superior to ceramics.
Moreover, such a study is also deemed as necessary to the development of novel marine materials. 2.

Asphalt mixture is a kind of viscoelastic materials and it will occur complicated deformation under all kinds of stress and it depended temperature and time greatly.
For research’s convenient, this paper use the theory of linear viscoelastic materials to asphalt mixture and the main method is to get viscoelastic parameters of of Burgers model by creep experiments.
Numerical Calculation ABAQUS is a kind of finite element software which has a strong nonlinear computational ability to materials’ numerical calculation, and the results can meet general scientific computing requirements.

Introduction As the main body of microeconomic operations and dominant force in social production, enterprises are not only the direct providers of material goods, but also the major producers of environmental pollutants.
In the links of production and business spending, enterprises turn natural resources into social material production as well as the products flow into the circulation areas of consumption.
From the self interest of economic man, enterprises' self-interest motivation in the pursuit of material wealth won't regard the interests of others and only take their own interests as the center, so even if their own behavior pollute the environment, destroy the resources and cause a loss to others and society, they will do the same to get benefit, while the others and society will pay the price instead.
