Load tracking with the arc-length method
Load tracking with the arc-length method
(OP)
Hi all,
How can I track the value of the load at each substep when using the arc-length method to solve a non-linear buckling problem? With the N-R method, the time is used to track the value of the load at a given substep but in the arc-length method, the time is not monotonic increasing ie. doesn't reflect the value of the load at the current substep.
The scope is to plot a load vs deflection curve.
