Crack propagation calculations in aircraft engines by coupled FEM-DBEM approach [PDF]
, 2012 New generation jet engines are subject to severe reduced fuel consumption requirements. This usually leads to thin components in which damage issues such as thermomechanical fatigue, creep and crack propagation can be quite important.

Mechanism of crack branching in the fatigue crack growth path of 2324-T39 Aluminium alloy
Fracture and Structural Integrity, 2015 The crack growth behavior in 2324-T39 aluminium alloy was experimentally investigated. Two types of crack branching were observed. The mechanism of an uncommon crack branching which results from the link up of secondary crack with the main crack was ...

Effect of different boundary conditions on the crack growth mechanism under cycling bending loads
, 2018 Sometimes, structural components are subjected to service conditions that have not taken into account at the design stage. If it is assumed that an initial flaw exists, according to damage tolerance philosophy the analysis of such components needs to be ...

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine
Advanced Materials, EarlyView.A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Mode I fatigue growth analysis of a sickle surface crack in a cylindrical bar
, 2006 The fatigue growth of a sickle-shaped surface crack in a metallic round bar under bending loading is examined. The flaw, located in a plane perpendicular to the longitudinal axis of the bar, is assumed to present an elliptical-arc shape during the whole

Advanced Materials, EarlyView.Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Advanced Materials, EarlyView.The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.
