TLDR
In this paper, a phase field approach is employed to model fracture in the matrix and the interphase zone of the polymeric nanocomposites (PNCs) while the stiff clay platelets are considered as linear elastic material.About:

A length scale insensitive phase-field damage model for brittle fracture
Jian-Ying Wu,Vinh Phu Nguyen +1 more
TL;DR: In this article, a phase-field regularized cohesive zone model (CZM) with linear softening law is applied to brittle fracture. But the model is not suitable for the case of nonlinear singularities (e.g., corners, notches, etc.).

Effects of Size and Aggregation/Agglomeration of Nanoparticles on the Interfacial/Interphase Properties and Tensile Strength of Polymer Nanocomposites
TL;DR: It is found that a thick interphase cannot produce high interfacial/interphase parameters and significant mechanical properties in nanocomposites because the filler size and aggregates/agglomerates also control these terms.

Modeling dynamic fracture of solids with a phase-field regularized cohesive zone model
Vinh Phu Nguyen,Jian-Ying Wu +1 more
TL;DR: In this article, an extension of the phase-field cohesive zone model for static fracture to dynamic fracture in brittle and quasi-brittle solids is presented, and the model performance is tested with several benchmarks for dynamic brittle and cohesive fracture.

Revisiting brittle fracture as an energy minimization problem
TL;DR: In this paper, a variational model of quasistatic crack evolution is proposed, which frees itself of the usual constraints of that theory : a preexisting crack and a well-defined crack path.

A phase field model for rate-independent crack propagation: Robust algorithmic implementation based on operator splits
TL;DR: In this paper, a variational framework for rate-independent diffusive fracture was proposed based on the introduction of a local history field, which contains a maximum reference energy obtained in the deformation history, which may be considered as a measure for the maximum tensile strain obtained in history.
