Evaluation of dynamic fracture toughness of a bonded bi-material interface subject to high-strain-rate shearing using digital image correlation [PDF]
Engineering Fracture Mechanics, Vol. 241 (2021), 107391, 2020 High-strain-rate shear tests were conducted on a three-layered bonded test piece comprising a central aluminum layer with PMMA resin layers bonded on both sides. Upon calculating the displacement field and the strain field using digital image correlation (DIC), the crack tip was located, and the fracture toughness was evaluated at the Aluminum/PMMA ...

Predicting fatigue crack growth rate in a welded butt joint: The role of effective R ratio in accounting for residual stress effect [PDF]
, 2009 A simple and efficient method is presented in this paper for predicting fatigue crack growth rate in welded butt joints. Three well-known empirical crack growth laws are employed using the material constants that were obtained from the base material ...

Stress intensity factors of interfacial cracks
Engineering Fracture Mechanics, 1993 Abstract A comparison of mode I and II stress intensity factors at the interfacial crack tip arising from different applied loads and edge dislocation is made. Under the action of point load the stress intensity factor oscillates with the distance from the position of applied load to the crack tip, but there is no oscillation in the stress intensity ...

Stress intensity factor solutions for CTS mixed mode specimen
Fracture and Structural Integrity, 2019 The Compact Tension Shear (CTS) specimen is used to study fracture and fatigue under mixed mode I/II loading conditions. The K solution available in literature was developed for fracture studies and does not consider the effect of crack deflection.

Isotoxal star-shaped polygonal voids and rigid inclusions in nonuniform antiplane shear fields. Part II: Singularities, annihilation and invisibility [PDF]
International Journal of Solids and Structures 85-86 (2016), 76-88, 2016 Notch stress intensity factors and stress intensity factors are obtained analytically for isotoxal star-shaped polygonal voids and rigid inclusions (and also for the corresponding limit cases of star-shaped cracks and stiffeners), when loaded through remote inhomogeneous (self-equilibrated, polynomial) antiplane shear stress in an infinite linear ...
