When these biomaterials are implanted into the body, the initial interaction occurs at the surface of the materials, So in most of the cases, the surface properties of the HA play an important role in its application as its surface is in direct contact with the environment (body fluids,etc.)
Materials and Methods 2.1 Materials An amorphous Ca phosphate way was adopted to prepare HA powder [8].

A 3D numerical model was developed to analyze the deformation and stress characteristics of HDPE material circular net cage exposed to waves, using the finite element method (FEM).
But when the HDPE material is aging and the yield stress decreases, the failure may happen.

Introduction Currently the vast majority of materials people used contain more than two groups.
This process has important influence on the property of materials [1, 2].
As an important part in the material science, the study of interface diffusion is of great theoretical and practical value.

When keeping true stress of the asphalt concrete constant under load, then the viscosity behavior of materials mainly presents creep, rather than relaxation, two possible situations are discussed below.
The total strain can be expressed as: (4) Situation two, when , materials yield occurs, true plastic strain occurs in the material, it can be expressed as: (5) is true plastic strain, is the onset of plastic strain, is Poisson's Ratio.
