A shifted energy barrier approach for phase-field modeling of tensile-dominated brittle fracture
Yaode Yina, Yaode Yin, Luigi Greco +3
The classical AT1 phase-field model contains an intrinsic energy barrier for crack nucle ation, which makes the predicted strength depend on the fracture toughness and the regulari…

An efficient active-stress electromechanical isogeometric shell model for muscular thin film simulations
Michele Torre, Simone Morganti, Alessandro Nitti +4
We propose an isogeometric approach to model the deformation of active thin films using layered, nonlinear, Kirchhoff Love shells. Isogeometric Collocation and Galerkin formulation…
