Abstract
•Novel implementation in Julia of an efficient finite element modelling framework for the numerical simulation of frictional contact interactions between beams and rigid surfaces;•Contact surface represented by discrete Signed Distance Field, predefined in 3D background mesh;•Evaluation of code robustness and computational speed by comparison with the original Matlab code and the commercial software Abaqus;•Introduction of additional mechanical contributions to model constraints and viscous damping;•Cardiovascular application simulating the deployment of a braided stent within an idealized artery.
