Bio‐Inspired Molecular Events in Poly(Ionic Liquids)
Advanced Functional Materials, EarlyView.Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance
Advanced Functional Materials, EarlyView.A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Strain hardening of rail steel
Deformation and Fracture of Materials, 2023Based on the results of studying the evolution of structural-phase states and the dislocation substructure of rail steel under uniaxial compression deformation up to a degree of 50%, a quantitative analysis of the hardening mechanisms of this steel under compression conditions has been performed.

Hardening curves for materials with strain hardening
Russian Engineering Research, 2016Experimental hardening curves are plotted for the analysis of the cutting process in strain-hardening materials. As examples, approximate formulas for specific carbon steels are presented.

Nature, 1966
FRACTOGRAPHIC studies1–3 using optical and electron microscopy have shown that, for many metals, high-strain fatigue endurance is determined by crack propagation of the type designated stage II by Forsyth4. This is contrary to the statistical argument put forward by Gittus5 and the dislocation intersection model of Gilman6, neither of which is in ...

Journal of Mechanical Engineering Science, 1972
Continuous and interrupted room temperature compression tests were carried out on geometrically similar specimens of duralumin, pure copper and lead, using steel and ebonite dies. Significant differences in strain-hardening rate were ascribed to heat-transfer during deformation.

Strain Hardening and ‘Strain-Rate Hardening’
1982The limitations of power-law strain hardening and ‘strain-rate hardening’ descriptions are reviewed. It is found that significant advantages can be gained by using, instead, the Voce relation, especially in the proposed modification that accounts for the rate sensitivities of flow stress and of strain hardening.

Strain hardening in liquid-particle suspensions
Physical Review E, 2005The behavior of a liquid-particle suspension induced to sheared motion was analyzed by numerical simulations. When the velocity (strain) of the suspension began to increase, its viscosity first stayed almost constant, but increased then rapidly to a clearly higher level.

On Strain-Hardened Circular Cylindrical Shells
Journal of Applied Mechanics, 1960A consistent kinematic hardening theory termed complete hardening, based on a Tresca initial yield condition, has been applied to determine the general flow laws for rotationally symmetric shells. Representative “long” and “short” cylindrical shell problems with zero axial load are solved using complete hardening and a simpler but approximate kinematic
