EndoBeams.jl: A Julia finite element package for beam-to-surface contact problems in cardiovascular mechanics
Advances in Engineering Software(2022)
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.
