A metal axle with second moment of area of 3,313.5 mm and radius of 15 mm is subjected to two consecutive loading blocks: (i): a pure bending moment of 100 kN mm and (ii): the bending moment of (i) plus a constant axial stress of 100 MPa Calculate the appropriate cyclic stress amplitude to apply for each case in order to be able to use a fully reversed S-N curve to estimate cycles to failure, taking account of the influence of mean stress using the modified Goodman equation and assuming the ultimate tensile strength is 1,000 MPa.

Transcribed Image Text:Q.3.
A metal axle with second moment of area of 3,313.5 mm and radius of 15 mm is subjected to two
consecutive loading blocks:
(i): a pure bending moment of 100 kN mm and
(ii): the bending moment of (i) plus a constant axial stress of 100 MPa
Calculate the appropriate cyclic stress amplitude to apply for each case in order to be able to use a
fully reversed S-N curve to estimate cycles to failure, taking account of the influence of mean stress
using the modified Goodman equation and assuming the ultimate tensile strength is 1,000 MPa.
ANS: (i) Sao = 452.7 MPa (ii) Sao = 503 MPa
