Introduction Polymeric materials exhibit viscoelastic behaviors in physical environments and/or under practical mechanical loading.
Creep in polymeric materials is a complex phenomenon, which depends on both material properties and external parameters such as stress level, temperature and humidity.

The results indicated that the criterions and the sensitization degree of material have a corresponding relationship, and can reflect the change of sensitivity on the low-sensitized materials to intergranular corrosion sensitively and quantitatively.

Compressive specimens were electro-discharge machined from the as-received materials.
One interesting study by Han Zhao[7] shows that the sharp rise in plastic strength of materials would be related to those points.

Introduction Human bone is an orgnic-bioorganic composite material consisting mainly of collagen proteins and hydroxyapatite.
To duplicate this high performance of natural bone, artificial bone materials have been produced in which organic substrates such as poly- (lactic acid), poly(L-lactide), peptide-amphiphile nanofibers, reconstituted collagen, and inorganic substrate have been used in the mineralization[10-19].
