Lecture 35: Fatigue

[@blackdog4175]

I don't understand instead of this much quality lecture on TH-cam why people are wasting money on coaching centre in India?

[@saching9746]

Excellent quality lectures. Expecting more such lectures from you. These videos helped me with my Mtech .Thank you so much

Sir,
Your movie lecture is very good. Thank you for guiding people, but I would like to make a request that you make a movie that is grade 60 compliant to ASTM 615 and also understand the integrity of this standard. So this standard is written here so under that we'll go here and with that we'll go here and do this test.
Regards,

Sir, why fatigue failure occurs if the applied stress is well below the yield stress?

[@snehajain4334]

Tensile stress causes a small crack to open up and the crack slowly and continually opens up with application of tensile stress. The stress required to open the crack is well beyond the Yield stress.

@@snehajain4334 how the crack is intiated at the first place is the question I think

[@snehajain4334]

@@aravindkumar6631 i don't understand what you mean, but if you are asking how the initial crack occurred , it is due to defects in manufacturing.

why endurance limit exists for Fe and not for Al?

[@snehajain4334]

Aluminium alloy is more ductile.
