Phase field modelling of crack propagation in functionally graded materials
TL;DR: A phase field formulation for fracture in functionally graded materials builds upon homogenization theory and accounts for the spatial variation of elastic and fracture properties and identifies material gradient profiles that prevent unstable fracture and enhance crack growth resistance.
Journal ArticleDOI
Adaptive phase-field modeling of brittle fracture using the scaled boundary finite element method
Hirshikesh,A.L.N. Pramod,Ratna Kumar Annabattula,Ean Tat Ooi,Chongmin Song,Sundararajan Natarajan +5 more
TL;DR: Numerical results show an improvement in the computational efficiency in terms of the number of elements required in the standard PFM without compromising the accuracy of the solution.
Journal ArticleDOI
A FEniCS implementation of the phase field method for quasi-static brittle fracture
TL;DR: The present work discusses the implementation of the phase field method for brittle fracture within the open-source finite element software, FEniCS, which provides a framework for the automated solutions of the partial differential equations.
Journal ArticleDOI
Modeling crack propagation in variable stiffness composite laminates using the phase field method
TL;DR: In this paper, the role played by the orientation of the fiber and the inter-fiber spacing on the fracture pattern in the composite is investigated. But the main objectives of this work are: (a) to study the crack propagation path and (b) to investigate the influence of the fibre-matrix interface on the crack path.
Journal ArticleDOI
Adaptive phase field method for quasi-static brittle fracture using a recovery based error indicator and quadtree decomposition
TL;DR: In this paper, an adaptive phase field method is proposed for crack propagation in brittle materials under quasi-static loading, which is based on the recovery type error indicator, combined with the quadtree decomposition.
