Fracture Toughness and Fatigue Threshold of Tough Hydrogels
ACS Macro Letters, 2018 Hydrogels of numerous chemical compositions have achieved high fracture toughness on the basis of one physical principle. As a crack advances in such a hydrogel, a polymer network of strong bonds ruptures at the front of the crack and elicits energy dissipation in the bulk of the hydrogel.

Exceptional fracture toughness of CrCoNi-based medium- and high-entropy alloys at 20 kelvin [PDF]
Science, 2022 CrCoNi-based medium- and high-entropy alloys display outstanding damage tolerance, especially at cryogenic temperatures. In this study, we examined the fracture toughness values of the equiatomic CrCoNi and CrMnFeCoNi alloys at 20 kelvin (K).

ESTIMATION OF WOOD TOUGHNESS IN BRAZILIAN TROPICAL TREE SPECIES [PDF]
Engenharia Agrícola, 2020 Wood has been used for several purposes such as in civil and rural construction. Knowing wood mechanical behavior under short-term loading is essential for safer structural designs. However, wood toughness is a mechanical property little investigated for

Processing and mechanical characterization of Al2O3/Ni and Al2O3/Co composites by pressureless sintering of nanocomposite powders [PDF]
Processing and Application of Ceramics, 2018 Al2O3/Ni and Al2O3/Co nanopowder mixtures (with 3 vol.% of metallic phase) were synthesized by heterogeneous precipitation method. In order to increase the green strength, polypropylene carbonate (PPC) was used as a binder while preparing green compacts.

Quantitative prediction of effective toughness at random heterogeneous interfaces [PDF]
, 2013 The propagation of an adhesive crack through an anisotropic heterogeneous interface is considered. Tuning the local toughness distribution function and spatial correlation is numerically shown to induce a transition between weak to strong pinning ...
