It is sometimes very difficult to define a reliable FE model for real mechanical structure, because a lot of its system parameters or properties are uncertain [10].
Particularly, in the case of FE analysis, the mechanical properties of the used materials are very hard definable, and therefore an important source of uncertainty [11].
The uncertainties in the model parameters can be taken into account by representing the affects of scatter by fuzzy numbers with their shape derived from statistical data.
Due to this numerical approach, we can analyze mechanical, technological, service and economic properties of the investigated structures more authentically.

However conventional fusion welding processes often leave defects, such as porosities and hot cracks in the weld, which declines the mechanical properties of magnesium alloys [3].
The thermal cycle or temperature distribution is a key factor to affect the plastic flow and the final microstructure and mechanical properties of the weld using FSW.
Wang et.al [6, 7] measured the thermal cycle of aluminum alloys during FSW by means of embedding thermocouples and found that thermal cycle influences the mechanical properties of weld by changing the size and distribution of the precipitates.
The aim is to establish a base to correlate the temperature distribution of FSW with the dynamical recrystallization, microstructure and mechanical properties for the weld along different locations for magnesium alloys.

In addition, due to limitations in computing power as well as the complexity of temperature dependent material properties, several assumptions were required to allow for the FE model to converge.
The strain gauges were placed on the side arm and middle arm (see Figure 1) to determine how the varying wall thickness would affect the development of residual strain.
Although the results presented in the current study and in [18] provide valuable data regarding stress development in castings, the studies are limited by the precision of the applied techniques (i.e. strain gauges and thermal imaging) as well as the accuracy of the temperature dependent material properties.

The research results of mechanical properties, hydrogen embrittlement and corrosion fatigue of new and corroded galvanized wires which were used in cable-supported bridges were summarized.
Mechanical Properties of Corroded Wires Table 1 illustrates the progression of the corrosion of cable wires through four levels, which can easily be identified visually, and are the basis for a steel wire inspection.
Shun-ichi Nakamura, Keita Suzumura and Toshimi Tarui did some research on the mechanical properties of corroded galvanized steel wires [20].
It is known that non-diffusive hydrogen does not affect hydrogen embrittlement, although a further study is required to clarify how non-diffusive hydrogen affects fatigue strength. 　　
It was found that the stress would not affect the amount of diffusive hydrogen.

The S-N curve and the fatigue limit are basic parameters defining fatigue strength properties of materials subject to cyclic load.
