XFEM-CZM combination for the numerical treatment of ductile fracture

, 2019
Résumé Ce travail porte sur la prédiction numérique de la résistance résiduelle de grandes structures métalliques (aéronautiques, navales) lorsqu'elles sont soumises à des surcharges accidentelles (collision, choc, impact d'oiseaux, etc.). L'enjeu de cette étude consiste à reproduire dans une méthodologie unifiée, basée sur la méthode des éléments ...

Assessment of Reinforcement Effect of FRP‐Strengthened Shield Segment Joint Based on the CZM Model

Advances in Civil Engineering
As the weakest link in the shield segment, the reinforcement and repair technology of shield segment joint has received widespread attention. In this study, an finite element model utilizing a cohesive zone model (CZM) was constructed to simulate the mechanical behavior of the shield segment joint during the whole fracture process.
