EndoBeams.jl is a Julia finite element package for beam-to-surface contact problems. The package is based on a 3D FE corotational formulation for frictional contact dynamics of beams where the target surface, supposed rigid, is described implicitly using a Signed Distance Field (SDF), predefined in a volumetric grid.
First, add the Endobeams.jl package with using Pkg, Pkg.add(url="https://github.com/beatricebisighiniEMSE/EndoBeams.jl").
Run one of the examples present in the "examples" folder:
angle.jl: Right-angle cantilever beam subject to out-of-plane loading;ring.jl: Impact of a ring against a rigid surface;net.jl: Dropping a net on a rigid sphere;stent.jl: Deployment of braided stent.
main: The package version from [1];EndoBeams 2.0: Last package version;FEM-stent-deployment: Stick-slip friction + all the utils to perform patient-specific simualation of braided stent deployment (one case provided);
