Foams[3], magnetorheological fluids, porous materials and sandwich structures are the typical impact resistant materials.
However, these materials are sensitive to impact damage [1, 5-7], which can't endure long-term continuous uses and generally are horniness materials.

Introduction In recent year, the environmentally friendly raw materials have been interested and developed rapidly; as follows the growth of environmentally friendly raw materials has higher interest, especially in the application of biodegradable material from renewable sources [1].
The chemical composition from EDXRF report that the biological materials which contain Hydrogen (H), Carbon (C), Nitrogen (N) and Oxygen (O) have the highest concentration, then the other elements, which shown in Table 1 and Fig. 1.

Firstly, it briefly introduces the background of creep damage for P91 materials.
To analyze the complex of creep deformation and rupture, the creep damage constitutive equations should be able to depict the behaviour of material, especially for predicting the lifetime of materials, within the frame work of continuum damage mechanics (CDM).

This paper adopts different material properties of concrete.
Fig. 3 Geometry model of arch dam and foundation Entire model contains three materials: concrete, low elastic modulus of concrete and rock foundation.
In addition, application of the low elastic modulus of high strength concrete has a certain feasible in theory, but it is difficult to selecting materials, concrete strength test is limited, there are less practical engineering examples.
