(1) the characteristics of Weibull distribution described above normal although the very broad application, but it has an obvious drawback (lack of), that is, the smaller the better to make the failure probability. Then part of the strength (or life) to zero. This physical concept is not true cause of the lack of reason is the symmetry of normal distribution curve. Materials or parts of the strength (or life) there is always a limit, such as material fatigue limit of materials with cracks there is a fatigue crack growth below the threshold value of AK or the AK material will not fail, or that it's a zero probability of failure Therefore, from the physical concept, describes the probability distribution of these performance indicators should not be normal,<a href="http://www.airjordansshoescheapnike.com" target="_blank">air jordan shoes cheap</a>, but should be skewed. One of the characteristics of Weibull distribution is that it fits this physical concept, it is the skewed distribution, when the strength (or life) is less than a certain value, the probability is zero in 1951 and 1952, published in the Weibull two articles, he considered the strength of the chain, which is a chain composed of a chain link.
