The effect of low-cycle fatigue on evolution of fracture mechanics parameters in residual stress field caused by cold hole expansion [PDF]
Fracture and Structural Integrity, 2019 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 holes.

Ductility of 3D printed concrete reinforced with short straight steel fibers
Virtual and Physical Prototyping, 2019 With the number of 3D printed concrete structures rapidly increasing, the demand for concepts that allow for robust and ductile printed objects becomes increasingly pressing. An obvious solution strategy is the inclusion of fibers in the printed material.

Characterization on crack propagation of nuclear graphite under three-point bending
Nuclear Materials and Energy, 2019 The fracture properties of graphite produced in China, named as CLG, were studied by performing three-point bending tests on center-notched beams. The load-deflection (P-δ) curves and load-crack mouth opening displacement (P-CMOD) curves of the beams in ...

Sum rules for $e^+e^- \to W^+W^-$ helicity amplitudes from BRS invariance [PDF]
, 1998 The BRS invariance of the electroweak gauge theory leads to relationships between amplitudes with external massive gauge bosons and amplitudes where some of these gauge bosons are replaced with their corresponding Nambu-Goldstone bosons.
