A Time-Integral Crack Propagation Model Considering Thickness Effect
IEEE Access, 2019 The crack propagation mechanism of thick plates is difficult to describe accurately, and thus, it is difficult to predict the lifetimes of thick plate structural cracks in extreme construction environments.

Modelling probabilistic fatigue crack propagation rates for a mild structural steel
Fracture and Structural Integrity, 2014 A class of fatigue crack growth models based on elastic–plastic stress–strain histories at the crack tip region and local strain-life damage models have been proposed in literature.

Fatigue Crack Propagation in Metals [PDF]
Nature, 1967 A RECENT paper by Pearson1 reports the results of crack propagation experiments on various metals, of which Young's moduli E range from 6.5 × 106 lb./in.2 to 30 × 106 lb./in.2. It was found that the fatigue crack propagation rates were sensibly equal when the applied stress f was a fixed proportion of E. I have recently obtained theoretical support for

Transforming Grain‐Boundary Brittle Precipitates to Ductility Pathways in Complex Concentrated Alloy
Advanced Science, EarlyView.By engineering graded BCC/L12 interfaces, brittle precipitates in a complex concentrated alloy enable sequential deformation, realizing gigapascal strength with >20% elongation to solve the strength‐ductility trade‐off. ABSTRACT Conventional wisdom holds that hard grain‐boundary (GB) precipitates embrittle structural alloys by acting as crack ...

Advanced Science, EarlyView.A novel strategy is developed by doping reduced graphene oxide (rGO) into a (HfZrTi)C medium‐entropy ceramic. This induces a hierarchical strain modification mechanism, synergistically inhibiting crack propagation at the microscale and dissipating stress at the mesoscale.

Difracción de rayos X y difracción de neutrones en estudios de fatiga y fractura de materiales [PDF]
, 2019 Conferencia invitada de Joseph F KelleherThe fatigue behaviour of polycrystalline metals is often studied through crack propagation analysis [1,2]. Nevertheless, understanding the mechanical processes that take place right at the crack tip [3,4] would ...
