Softening behavior of reinforced concrete beams under cyclic loading

A framework of elastic–plastic damaging model for concrete under multiaxial stress states

“…Although damage is inherently a non isotropic phenomenon, in order to overcome some of the dramatic convergence problems related to the computational implementations, many authors have commonly adopted an isotropic damage formulation, making use of a single scalar variable (Luccioni et al, 1996;Jirásek and Zimmermann, 1998;Brenchic and Gambarotta, 2001;Salari et al, 2004). Scalar models with two damage variables have also been proposed, in an attempt to distinguish between tension and compression damage mechanisms (Mazars, 1986;Faria et al, 1998;Comi and Perego, 2001;Marfia et al, 2004). Following the general formulation of Hansen and Schreyer (1994) and Murakami and Kamiya (1997), anisotropic damage models have been proposed introducing 4th or more frequently 2nd order tensors (Papa and Taliercio, 1996;Dragon et al, 2000;Sellier and Bary, 2002;Litewka and Debinski, 2003;Lü et al, 2004;Kuna-Ciskał and Skrzypek, 2004;Gambarotta, 2004).…”

A study on the contraction joint element and damage constitutive model for concrete arch dams

“…Kuna-Ciska and Skrzypek (2004) studied the anisotropic evolution of damage factors for elastic-brittle materials based on the theory of continuum damage mechanics (CDM) and the finite element method (FEM). Marfia et al (2004) analyzed the change in damage factors for reinforced concrete in the process of compressive and tensile softening. Mirzabozorg and Ghaemian (2005) proposed a damage constitutive model to describe the behavior of concrete under static and dynamic loads.…”
