Abstract
This paper describes a new solution procedure, the local arc-length
method, for structures with strain-softening materials
which is a development of the arc-length method. The new
procedure is based on using a constraint equation which uses
displacement parameters associated with the localised failure
zone in such structures. Numerical examples show that this
new procedure is more reliable than current versions of the
arc-length method.
