Residual stress effect on fatigue striation spacing in a cold-worked rivet hole
Matos, P. F. P. de; Moreira, P. M. G. P.; Pina, J. C. P.; Dias, A. M.; Castro, P. M. S. T. deThe residual stress effect due to cold-working is studied in relation to fatigue striation spacing. Cold-working introduces a compressive stress field around the hole reducing the tendency for fatigue cracks to initiate and grow under cyclic mechanical loading. It is known that fatigue lifetime assessment requires a detailed knowledge of the residual stress profile. X-ray diffraction and 3D finite element analy...
