A micromorphic phase-field model for brittle and quasi-brittle fracture
Ritukesh Bharali, Fredrik Larsson, Ralf Jänicke
The phase-field model for fracture, despite its popularity and ease of implementation comes with its set of computational challenges. They are the non-convex energy functional, var…
Phase-field fracture irreversibility using the slack variable approach
Ritukesh Bharali, Fredrik Larsson, Ralf Jänicke
In this manuscript, the phase-field fracture irreversibility constraint is transformed into an equality-based constraint using the slack variable approach. The equality-based fract…
Tangential differential calculus and the finite element modeling of a large deformation elastic membrane shell problem
Peter Hansbo, Mats G. Larson, Fredrik Larsson
We develop a finite element method for a large deformation membrane elasticity problem on meshed surfaces using a tangential differential calculus approach that avoids the use of c…
