Global cracking elements: a novel tool for Galerkin-based approaches simulating quasi-brittle fracture
A reorganized cracking-elements method, GCEM, models quasi-brittle fracture by making crack openings global unknowns through borrowed center-node degrees of freedom in 9-node quadrilateral elements.
