Prediction and Experimental Validation of the Influence of T-Stress on I–II Mixed-Mode Fracture in Rock

open access: yesAdvances in Civil Engineering
Traditional fracture criteria only consider the singular terms in the Williams expansion and neglect higher-order term coefficients, resulting in significant discrepancies between predicted and measured values.

Multiscale Polymer Composites: A Review of the Interlaminar Fracture Toughness Improvement

open access: yesFibers, 2017
Composite materials are prone to delamination as they are weaker in the thickness direction. Carbon nanotubes (CNTs) are introduced as a multiscale reinforcement into the fiber reinforced polymer composites to suppress the delamination phenomenon.

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)

open access: yesAdvanced 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 ...
