Although there have several other materials (such as timber, steel, and plastics) used for sheet-piles, reinforced concrete sheet-piles are the most common one in retaining walls.
This is the cause of filling materials used for construction are graded broken stones with short construction time, and the compactness of deep filling material is hard to reach the ideal state in such a short time.

Introduction Researchers have made efforts to improve the mechanical and electrical properties of micro-electronic materials[1~6].
However, many pure materials (such as silver, copper and aluminum) have high electric conductivity but very soft.

Usually there is an oxide layer covering the nanowire surface, and thus we have to consider the second last expression in eq. (1) where the subscripts B and O denote the boron and (boron) oxide materials ( OB III += , OB AAA += ).

Defining the Material Properties.
For the designing of the Inventor finite element analysis, the designers can choose the corresponding materials according to their needs in the style library of the software.
If none of the properties of materials are needed, we could create the properties of materials in the style editor.
In this thesis, it adopts the materials of Q235 steel to analysis the structure of the framework.

When the ‘freezing’ strain values of concrete materials was equal to or less than 1.96‰, the damage of the concrete turned to be aggravated slightly with the increase of the strain rate.
The concrete constitutive model after impact load Based on the strain equivalence principle[8], any constitutive relation of damaged materials could be derived from the constitutive equation of nondestructive materials under the uniaxial stress condition .By replacing the nominal stress of nondestructive constitutive relation with the effective stress after the damage; damage constitutive of concrete relationship was gat: (2) E was the elastic modulus, was the strain and D was the damage variables.

The tensile strength of ordinary cement-based materials is low, and the materials are easy to crack, which affect serviceability and durability of the structure.
Test materials The ECC material in tests consists of P • O42.5 ordinary Portland cement, quartz sand, tap water, polycarboxylate(superplasticizer), C-PVA fibers provided by Shanghai Royang Innovative Material Technologies Co., Ltd. and J-PVA fibers provided by Unitika (Shanghai) Ltd..
