Original Abstract

Two different non-iterative solving approaches for mechanical systems composed of elements with sawtooth constitutive laws have been described in the literature. The first algorithm called the load-unload (L-U) method removes the whole external load after every rupture event and linearly increases it again from zero until the next rupture event occurs. The second algorithm, called the force-relase (F-R) method, keeps the load unchanged after a rupture and redistributes the stresses from damaged elements until an equilibrium state has been reached. Then, the load may increase again.

Keywords
