Stress concentration reduction in an axially loaded rectangular bar with an elliptical hole
(2023-03-17)Two-dimensional finite element analysis was used for stress concentration factors estimation in a wide range of bar-ellipse height and height-width elliptical hole ratios in a tensile bar. Least squares ... -
Stress-Based Weibull Method to Select a Ball Bearing and Determine Its Actual Reliability
(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 ... -
Stress-strength Weibull analysis with different shape parameter B and probabilistic safety factor
(2020-11-05)Since products are subjected to a random variable stress-strength, their reliability must be determined using the stress-strength analysis. Unfortunately, when both, stress and strength, follow a Weibull distribution with ... -
Structural and magnetic behavior of oxidized and reduced fe doped LiNbO3 powders
(2018-02-26)Changes in structural and magnetic properties have been systematically induced in lithium niobate (LiNbO 3) powders, Fe-doped with different concentrations and thermally treated in oxidized and reduced states. A rather ... -
