Crack propagation in quasi-brittle materials by fourth-order phase-field cohesive zone model
Khuong D. Nguyen, Cuong-Le Thanh, Frank Vogel +2
A phase-field approach becomes a more popular candidate in modeling crack propagation. It uses a scalar auxiliary variable, namely a phase-field variable, to model a discontinuity…

Non-conforming multipatches for NURBS-based finite element analysis of higher-order phase-field models for brittle fracture
Khuong D. Nguyen, Charles E. Augarde, William M. Coombs +2
This paper proposes an effective computational tool for brittle crack propagation problems based on a combination of a higher-order phase-field model and a non-conforming mesh usin…
