Julia implementation of the arc-length method for nonlinear structural mechanics problems.
This implementation is based on a novel a extrapolated predictor recently proposed in Engineering Structures journal. You can download a PDF copy from ArXiv.
The main script is mymain.jl. The input files are prepared and tested. Uncomment the corresponding line in the main_arclength.jl file to run the script for a particular problem.
Some load-displacement curves computed with this code.

Lee frame
-
215-degree circular arch
-
Semi-circular arch with asymmetric loading
