Results show that the creep constitutive equation can better describe the deformation characteristics of materials, and the numerical simulations and experimental test points are in good agreement.
So obtaining suitable materials constants within constitutive equation is very critical for successful implementation of numerical simulation.
The conclusion above shows that the constitutive equation at temperature for 190°C can more accurately describe materials creep behavior.
The unified constitutive equation has been implemented into the finite element solver ANSYS through user subroutine CREEP and the materials constants of 190°C and 150MPa are chosen, the result at time of 10 h is plotted in Fig.2.

The axle materials showed a significantly lower fatigue crack growth rate than the wheel materials.
The deformation ratio in the wheel materials is relatively small in comparison to the axle materials.

Bioplastics are plastics that are synthesized from natural materials, so that they are easily degraded by microorganisms.
Therefore, in the manufacture of bioplastic from starch, it is necessary to have additional materials such as plasticizer and filler.

A continuum approach is used to model the macroscopic mechanical behavior of elastomeric materials reinforced with unidirectional fibers, in which the resin and fibers are regarded as a single homogenized anisotropic material.
The matrix and fiber materials are modeled as viscoelastic materials described by Eq. 1.
Such symbols are used to define the relaxation constant for matrix and fiber materials by adding superscripts of m and f, respectively.
Micromechanical modeling is used to evaluate the response of composite materials based on known viscoelastic behavior of composite constituents.

Filler materials-modifiers were aimed to help in solving these problems.
An advisability of using filler materials-modifiers comes from technical requirements and economic gain, which includes qualitative characteristics of materials adding to concrete or mortar, in condition of saving expensive concrete.
These materials are classified as surfactant-active substances (surfactants) [7].

Recent studies have investigated the development of biocomposite materials using natural fiber such as flax [1-2], bamboo [3], pineapple [4,5]Liu et al., 2005 W.
Bamboo fibre that is extracted from bamboo stem is abundantly found in Malaysia, traditionally used in various building materials, living facilities and tools.
The compounded materials were then ground with a crusher to prepared granules and were hot pressed molded using 125 Ton Hydraulic Hot Press.

The zirconia (ZrO2) ceramics stabilized with yttria (Y2O3), known as Y-TZP, present unique properties between the ceramics materials and their use has been diffused in dentistry [4].
When these materials are used in dental prosthesis components, they increase the useful life and the reliability of the devices [8, 9].

Through these experiments, it is found that the fretting fatigue strength decreased about 40~70% compared to the plain fatigue strength in two materials.
The objective of this study is to collect evaluation materials for the damage that occurred due to the experimental fretting fatigue in the material used in tubes for a steam generator in an atomic power plant.
