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 Initiation and Small Crack Propagation Behaviors of Simulated Specimens in a Ni-Based Superalloy

Metals
The role of notch geometry and stress levels on fatigue crack initiation and small crack propagation behavior in the FGH96 superalloy was investigated using groove and bolt hole simulated specimens at 500 °C.

An Elastocaloric Polymer with Ultra‐High Solid‐State Cooling via Defect Engineering

Advanced Science, EarlyView.
This work reports a defect‐engineering strategy that enables a record‐high adiabatic temperature change of up to 8.14 ± 1.76 °C in elastomers at an elevated temperature above 65 °C. Combined experimental and theoretical efforts reveal that increasing dangling‐chain defects nonmonotonically impacts the elastocaloric cooling performance of polymers due ...

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

Rib‐Reinforced Ultralight and Ultra‐Strong Shell Lattices

Advanced Science, EarlyView.
This study thoroughly reveals the relation between the curvature and stress direction of triply periodic minimal surface (TPMS) thin shell lattices and proposes a novel rib reinforcement design strategy to incorporate ribs along the line of asymptotes (LOA) and the line of principal curvatures (LOC) to enhance the strength of ultralight TPMS shell ...

Hierarchical Strain‐Modified Medium‐Entropy Carbide Ceramics Exhibit Exceptional Ablation Resistance up to 2400°C

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.
