Summary: This standard specifies the analysis of material fatigue data. Statistical properties of the test results within the meaning of this standard is closely related to the material properties under test conditions. In fact, a sample of a given material under different conditions may exhibit different failure mechanisms. Typically, the statistical properties of the data record represents a failure mechanism can be directly analyzed. In the case of non-uniform statistical properties, it is necessary for all instances by a single model for the distribution analysis. Failure of either the same stress level may also occur from Table seedlings from the inside. Corresponding to the statistical properties of the data corresponding to the mixing of different failure mechanisms. These results are more complicated because of the need for the type of comprehensive analysis, the standard will not be considered.

Introduction

As we all know, even in a very precise test control when the fatigue test results also showed a significant difference. This difference in part to Since in inconsistencies between the sample, including the slight differences in chemical composition, heat treatment, surface condition, and in part from the intrinsic engineering materials Feature --- fatigue failure of a random process. For more precise quantification of the inherent differences in the evaluation of mechanical design and structural fatigue properties of the material it is necessary. For laboratory Comparison of fatigue properties of materials, including the differences is necessary. GB/T 24176-2009/ISO 12107.2003 Metal fatigue test Statistics and analysis programs

1 Scope

1.1 Purpose This standard describes the fatigue test for statistical analysis of data and results. Purpose is in the number of high confidence and a sample test Fatigue properties of a given metal materials. 1.2 Performance Analysis for Fatigue This standard provides a method of analysis at different stress levels, using the linear relationship at the appropriate coordinate estimate material fatigue life. In particular should include the following. a) given to the fatigue life under stress; b) Given the fatigue life under fatigue strength. This standard, the term "stress" may be replaced by a "strain", the method of the strain of life characteristic analysis function is also effective. Strain control Fatigue strength test system according to strain to consider, in accordance with stress control stress test is usually understood. 1.3 Scope This standard is limited to a single analysis due to the fatigue failure mechanism and uniform characteristics exhibited by material fatigue data. Within the meaning of this standard test Test result statistical properties are closely related to the material properties under test conditions. In fact, for a given sample material under different conditions it may show different failure mechanisms. Under normal circumstances, the results of statistical data Total properties represents a failure mechanism can be analyzed directly. In the case of non-uniform statistical properties, it is necessary for all instances as a single division Cloth model is analyzed. Failure of either the same stress level from the surface can also occur from within. Corresponding data corresponding to different failure mechanisms of mixed statistics characteristic. These types of results because of the need for a comprehensive analysis of more complex, the standard will not be considered.
