Fracture is one of the most commonly encountered failure modes of engineering materials
and structures. Prevention of cracking-induced failure is, therefore, a major concern in …

This paper presents an overview of the theories and computer implementation aspects of
phase field models (PFM) of fracture. The advantage of PFM over discontinuous approaches …

Being able to model complex nucleation, propagation, branching and merging of cracks in
solids within a unified framework, the classical phase-field models for brittle fracture fail in …

In this paper, we develop a dual‐horizon peridynamics (DH‐PD) formulation that naturally
includes varying horizon sizes and completely solves the 'ghost force'issue. Therefore, the …

We present a phase field model (PFM) for simulating complex crack patterns including crack
propagation, branching and coalescence in rock. The phase field model is implemented in …

This paper proposes a phase field model for fracture in poroelastic media. The porous
medium is modeled based on the classical Biot poroelasticity theory and the fracture …

A phase field model for fluid-driven dynamic crack propagation in poroelastic media is
proposed. Therefore, classical Biot poroelasticity theory is applied in the porous medium …

In this paper, we propose an explicit phase field model for dynamic brittle fracture. The
mechanical field is integrated with a Verlet-velocity scheme, while the phase field is …

Compressive-shear fracture is commonly observed in rock-like materials. However, this
fracture type cannot be captured by current phase field models (PFMs), which have been …

We predict the macroscopic tensile strength and fracture toughness of fully exfoliated nano
silicate clay epoxy composites accounting for the interphase behavior between the …
