title = "A discrete quasi-static cyclic material model incorporating hysteresis for quasi-brittle materials",
abstract = "A quasi-static material model for quasi-brittle materials loaded in a cyclic tensile manner is presented in this paper. It incorporates not only the reduction of the stiffness and the permanent deformations but also the observed hysteretic phenomenon during unloading and reloading in the post-peak region. First, a continuum material model is generated by the coupling of a combined damage-plasticity model with a Preisach hysteresis model. Subsequently, this continuum model is discretised and implemented in the finite element program that can incorporate discontinuities into elements, using the partition of unity property of the finite element shape functions (PUM). Finally, the model is used to simulate a quasi-static cyclic tensile test of a double-edge notched specimen. The numerical results are compared with experimental results obtained by Gopalaratnam [1]. This comparison reveals that the proposed material model can capture the observed physical phenomena in an accurate manner.",
