DESCRIPTION
mean stress calculation, stress amplitude calculation,S-N curveTRANSCRIPT
a)
Calculate the mean stress and amplitude stress values to rank the fatigue lifetimes of the specimens.
Calculate the mean stress of specimen A.
Calculate the mean stress of specimen B.
Calculate the mean stress of specimen C.
Calculate the stress amplitude of specimen A.
Calculate the stress amplitude of specimen B.
Calculate the stress amplitude of specimen C.
Hence, the rank order is .
b)
Show the S-N plot.
