Stress Intensity Factor calculation from displacement fields

S. Beretta, L. Patriarca, S. Rabbolini

In the last two decades, visual image techniques such as Digital Image Correlation (DIC) enabled to experimentally determine the crack tip displacement and strain fields at small scales. The displacements are tracked during loading, and…

The effect of low-cycle fatigue on evolution of fracture mechanics parameters in residual stress field caused by cold hole expansion

Yury Matvienko, Vladimir Pisarev, Svyatoslav Eleonsky

Localized displacement measurements based on electronic speckle-pattern interferometry are used to obtain crack mouth opening displacement (CMOD), stress intensity factor (SIF) and T-stress values during crack growth around cold-expanded…

S-N curve modeling method of Aluminum alloy welded joints based on the fatigue characteristics domain

Li Zou, Xinhua Yang, Jianrong Tan, Yibo Sun

The scatter degree of the fatigue samples is reduced when the nodal force based structural method is used for steel welded joints, while it is still high for aluminum alloy welded joints. Statistical method and rough set theory is used to…

Fatigue failure of welded connections at orthotropic bridges

Z.H. Qian, D. Abruzzese

Orthotropic decks were applied to the long span bridges after World War II due to several advantages, such as light weight, high strength, few deck joints, durability, rapid construction, life-cycle economy. The fatigue problem of…
