INTRODUCTION Weibull distribution [1] is a well-established characterization tool in the field of modeling failure times and WebIt is shown that the technique is appropriate for analyzing 50 dynamic fatigue results over four decades of stressing rate, and gives a Weibull modulus with a confidence level similar to that for a randomly chosen set of simple strength test specimens. Similar results were obtained with an analysis of static fatigue tests. oqr review ssa https://jasonbaskin.com
