Accelerated Life Testing (ALT Video-1)

[@kamyarghods2429]

good initial insight about the accelerating methods

Thank you!🙏

7:27 why the stress vs time graph is shown as linear? Everywhere else log scale of stress and time was linear. Specific reason? Equation AF = to/ts is valid for any relation between stress and time linear or power law.

Many thanks for the upload ... very helpful

Glad it was helpful! Appreciate your feedback.

Thank you sir for video on ALT, request you to do on HASS & HALT aswell.

Thank you very much Sir. Clear explanation. I am trying to develop a ALT model on power cord cable/wires. The working mode is mainly flexing of cable and understand when the continuity breaks or the insulation fractures. Can you advise me if there is any model already exist for this application ? Thank you

[@instituteofqualityandrelia7902]

If the failure mode is mechanical flexing, perhaps power law or inver power law may work. If this is related to temperature, Arrhenius or Eyring model would be appropriate. Try to find out which one fits your data.

Well explained. I think the sound level could be increased. Also may be few examples on how to analyze the test results will help. Thanks for sharing.

[@instituteofqualityandrelia7902]

Thanks Vivek. The level is decided considering all viewers. Also, consider that this is the first video in the series of ALT. I have mentioned in the video about examples in forthcoming videos.

Excellent video!!! I have enjoyed a lot because of clear cut explanations!!! Can you suggest me any book for reading please? I am 17 yo and your video inspired me a lot to work in the field of reliability analysis

[@instituteofqualityandrelia7902]

Thank you! ALT Book by Brian Dodson could be a good choice!

What is qualitative and quantitative alt

[@instituteofqualityandrelia7902]

In qualitative ALT, no predictions are made or possible. In quantitative ALT, our objective is to predict reliability at normal operating conditions, but testing is done at elevated stress levels.

great explanation Thank you
