eFunda Factors Affect Fatigue Life

Since the fatigue life is closely related to the condition of surface,many researchers devote their effort to surface treatments.Generally speaking,treatments that produce compress residual stress at the surface have positive impact on the fatigue life and vise versa.Many widely used surface treatments may affect the fatigue in different ways.eFunda Factors Affect Fatigue LifeSince the fatigue life is closely related to the condition of surface,many researchers devote their effort to surface treatments.Generally speaking,treatments that produce compress residual stress at the surface have positive impact on the fatigue life and vise versa.Many widely used surface treatments may affect the fatigue in different ways.The effect of manufacturing defects on the fatigue life of Jul 01,2020 Influence of Manufacturing Conditions on Fatigue Life of#0183;The influence of manufacturing porosity and lack of fusion defects on the fatigue resistance of SLM processed Ti-6Al-4V was investigated in detail.By using X-ray tomography,an accurate characterization of the defects was realized in terms of
