dc.description.abstract | Applying Goodman, Gerber, Soderberg and Elliptical failure theories does not make it possible to determine the span of failure times (cycles to failure-Ni) of a mechanical element, and so in this paper a fatigue-life/Weibull method to predict the span of the Ni values is formulated. The input’s method are: (1) the equivalent stress ( eq) value given by the used failure theory; (2) the expected Neq value determined by the Basquin equation; and (3) theWeibull shape and scale parameters that are fitted directly from the applied principal stress 1 and 2 values. The e ciency of the proposed method is based on the following facts: (1) the and parameters completely reproduce the applied 1 and 2 values. (2) The method allows us to determine the reliability index R(t), that corresponds to any applied 1i value or observed Ni value. (3) The method can be applied to any mechanical element’s analysis where the corresponding 1 and 2, eq and Neq values are known. In the performed application, the 1 and 2 values were determined by finite element analysis (FEA) and from the static stress analysis. Results of both approaches are compared. The steps to determine the expected Ni values by using theWeibull distribution are given. | es_MX |
