Wood plastic composite (WPC) is defined by American Society for Testing and Materials (ASTM) as "a composite mainly made from wood flour or fiber and plastic" [1].
With good bond property, excellent thermal stability, being easy mixed with any other materials, and lower price, ethylene vinyl acetate (EVA) is a basic polymer of the hot-melt adhesive [3].
Experimental Materials.
Some researches show that EVA has a broad application with non-polar materials, polar materials and metal.

Compared with other materials, titanium alloys show better biocompatibility and tribological properties, and are widely used in medical implants.
Titanium alloy materials with low oxygen and high comprehensive mechanical properties can be prepared by controlling the processes of powder preparation, sintering and hot forming in inert atmosphere., Provide process basis and technical support for the preparation of powder metallurgy and rapid prototyping titanium alloy materials.
The relevant systems of powder consolidation and heat treatment need to modify the thermodynamic characteristic data and phase distribution of materials.

It is assumed that the mechanical properties of materials obey the Weibull statistics [3].
According to strain equivalent theory, the constitutive relation of damaged materials can be obtained by comparing the theoretic stress of perfect materials.
It is 0 0 )1/(/~/ ED EE −=== σσσε (1) during which E and E0 are elastic modulus of damaged materials and that of materials before damage, respectively, D is a damage parameter.
