A Phase‐Field Model for Quasi‐Dynamic Rupture Nucleation and Propagation of In‐Plane Faults

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Computational modeling of faulting processes is an essential tool for understanding earthquake mechanics but remains challenging due to the structural and material complexities of fault zones. The phase‐field method has recently enabled unified modeling of fault propagation and off‐fault damage within a fracture‐mechanics‐based framework ...

Interface crack kinking in composites materials

, 2018
Composites are often exposed to severe loading conditions which later may lead to crack formation and propagation. The interface crack is explored in this study by employ the hypothesis of linear elastic fracture mechanics and finite element methods.

The Effect of Veil Type and Laminate Architecture on the Mechanical and Dynamic Performance of Aramid Fiber Interlayered Thermoplastic Veil/Epoxy Composites: A Comprehensive Evaluation

Polymer Composites, EarlyView.
Graphical summary of the aramid fiber/thermoplastic veil laminates: (a) H‐2/1 and H‐2/2 hybrid architectures, (b) contrasting FG and PI/aramid microstructures, (c) flexural stiffness ranking, and (d) damping response, illustrating that fine‐glass (FG) veils maximize stiffness while PEI, PI, and PEEK veils maximize damping, with PPS providing an ...

A crack driving force criterion for the prediction of interface crack kinking in thin-film composites

, 2003
Interfacial fracture mechanics is a relatively new field with many issues that have not yet been resolved. One such issue is the ability to accurately predict whether or not a bimaterial interface crack will propagate along the interface, kink into the ...

Influence of Hybrid Co‐wrapped Yarn Structure on the Energy Absorption and Crack Propagation Resistance of Fiber‐Reinforced Composites

Polymer Composites, EarlyView.
Helical wrapping of polyamide around E‐glass fibres deflects and bridges impact‐driven cracks, arresting damage that would otherwise propagate catastrophically in conventional side‐by‐side hybrid yarns. ABSTRACT Hybrid cowrapped (CW) yarns were engineered to enhance the impact resistance and damage tolerance of fiber‐reinforced composites.
