Adaptive isogeometric analysis of high-order phase-field fracture based on THB-splines

Year: 2026

Type: article

Abstract: • We provide a fast adaptive isogeometric framework for phase-field brittle fracture. • We use THB splines and admissible refinement for adaptive meshing. • We use the AT1 and AT2 fracture model of second and fourth order in our framework. • Results are compared on uniform and adaptive meshes, for four phase-field models. • A speed-up of factor 10-13 is obtained compared to the baseline.
