Fatigue-Life Prediction of Mechanical Element by Using the Weibull Distribution
Piña Monarrez, Manuel Román (2020-09-13)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 ... -
Probabilistic Linear Time-Dependent Stress Beam Analysis and Its Stress-Strength Reliability
Piña Monarrez, Manuel Román (2021-04-12)Based on the principal stress values generated by the bending beam, the material’s strength required at 10^6 cycles is determined depending on time. To determine the stress/strength reliability (R(t)), the stress distribution ... -
Weibull S-N Fatigue Strength Curve Analysis for A572 Gr. 50 Steel, Based on the True Stress—True Strain Approach
Piña Monarrez, Manuel Román (2020-08-18)In this paper a Weibull methodology to determine the probabilistic percentiles for the S-N curve of the A572 Gr. 50 steel is formulated. The given Weibull/S-N formulation is based on the true stress and true strain values, ...
