Allowable Stress Range Calculation

It is home work, so you should at least try to get a solution and if it is wrong we shall help you to find the errors but 1st start to think how to solve your problem

The problem is easy and very simple, and you can solve it by yourself if you read the attached pages from ASME B31.1, Para. 102.3 Allowable Stress Values and Other Stress Limits for Piping Components: ASME_B31.1-_Para 102.3.

thanks a lot sir,,,

i was looking for exact place , where i can get the solution for this som.

special thanks for attaching this file....

so please tell me..

SA p f (1.25Sc + 0.25Sh) in this formula ..when only sc value is known then how i can calculate the SH.

and what value to be taken for f ?

thanksss a lot for helping.

sir got the value of F to be taken..for 60000 life cycles as per formula

f

p 6/N0.2 £ 1.0

be taken the value of f is comming 1.58 ..is it right ?

and my second problem is as told befor when sc is known hot to calculate sh ?
