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 ... -
Reliability by Using Weibull Distribution Based on Vibration Fatigue Damage
Piña Monarrez, Manuel Román; 187061; Barraza-Contreras, Jesús Manuel; Torres-Villaseñor, Roberto C. (2023-09-14)In this paper, a Weibull probabilistic methodology is proposed with an approach to model vibration fatigue damage accumulation using two parameters: Weibull distribution and a nonlinear fatigue damage accumulation model. ... -
Stress-Based Weibull Method to Select a Ball Bearing and Determine Its Actual Reliability
Piña Monarrez, Manuel Román (2020-11-16)Since the designed bearing’s reliability of 90% was determined in a lab environment, it does not represent the actual used environment. In this paper, a new methodology to determine the actual reliability that corresponds ... -
Vibration Fatigue Life Reliability Cable Trough Assessment by Using Weibull Distribution
Piña Monarrez, Manuel Román; 187061; Barraza-Contreras, Jesús Manuel; Villa-Señor, Roberto C. (2023-03-30)In this paper, the formulation to incorporate the used vibration profile, the stress generated by the product’s application, mass, and the resonance frequency is given. After that, based on the vibration output data, the ... -
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, ...
