Weibull distribution using the fatigue test as an example (survival/failure/reliability analysis)
In this video we take a closer look at the Weibull distribution, which is often used in failure analysis to describe the failure of mechanical or electronic components.
00:00 Stress-cycle curve (Wöhler curve)
02:34 Cumulative frequency
04:13 Frequency (histogram)
05:17 Relationship between frequency and cumulative frequency
05:57 Relative frequency
06:59 Probability
07:38 Corrected probability (population and sample)
10:54 Weibull distribution
13:07 Determination of the probability
15:02 Determination of the Weibull modulus and the scale parameter
17:00 Evaluation of the data (Weibull plot)
19:41 Characteristic lifetime
20:28 Weibull density function
22:03 Mean time to failure (empirical expected value)
23:03 Sample variance (empirical standard deviation)
24:18 Expected value and standard deviation
25:22 Probability of survival (reliability)
27:14 Absolute failure rate
28:47 Relative failure rate (hazard function)
30:57 Derivation of the hazard function
33:34 Selected Weibull distribution functions in comparison
34:43 Bathtub curve
36:31 Weibull distribution with failure free time

I can't believe that how such a important video has only few view and likes.. it should go viral at very fast rate.

Im thinking the same here
By far, one of the Weibull tutorials online. I highly appreciate you doing "from scratch" derivations and using example data. Excellent job.

I'll add it to my to-do list, but I have other projects to do at the moment.
great video. Congratulation . just a question. How can I generate the graph of frequency vs. load cycles with Stata ?

Thank you for the congratulations and for watching the video! I'm glad you enjoyed it. 😊 Unfortunately, I can't help you with Stata.
