摘      要：We propose an isogeometric approach to model the deformation of active thin films using layered, nonlinear, Kirchhoff-Love shells. Isogeometric Collocation and Galerkin formulations are employed to discretize the electrophysiological and mechanical sub-problems, respectively, with the possibility to adopt differ- ent element and time-step sizes. Numerical tests illustrate the capabilities of the active-stress-based approach to effectively simulate the contraction of thin films in both quasi-static and dynamic conditions. © 2024, The Authors.
