Ductile Failure Prediction of Friction Stir Welded AA7075-T6 Aluminum Alloy Weakened by a V-notch [PDF]
Journal of Stress Analysis, 2019 With increasing applications of the Friction Stir Welding (FSW), a proper study of the fracture behavior is required. In this research, fracture behavior of AA7075-T6 alloy joint made by FSW is investigated by evaluat-ing a fracture test on the ...

Nonlocal Criteria for Brittle and Quasi-Brittle Fracture of Geomaterials and Rocks
E3S Web of Conferences, 2018 Nonlocal criteria are used for prediction materials and rock mass failure near stress concentrations (pores, faults, openings, excavations). A common property of nonlocal fracture criteria is the introduction of the intrinsic material length ...

Criteria for impulsive rock fracture
Geophysical Research Letters, 1980 Explosive or percussive breakage of rock relies on impulsive rock fracture and both the fracture stress and fracture energy under such conditions are observed to be significantly greater than measured quasi‐statically. The implication of rate dependence has been verified in recent tensile fracture studies and in the present report this data has been ...

Rock Fracture Mechanics and Fracture Criteria
This open access book delves into the realms of geotechnical engineering and solid mechanics. In order to establish fracture parameters that are both relevant and conducive to safety, the book extensively investigates the fracture mechanical properties of mode I, mode II, and mode III in brittle rock materials.
