“…Despite the complexity, this approach to modelling of concrete has been widely adopted by several researchers, e.g. Simo and Ju [2], Yazdani and Schreyer [3], Luccioni et al [4], Lee and Fenves [5,6], Meschke et al [7], Faria et al [8], Hansen et al [9], Addessi et al [10], Ung-Quoc [11], Jefferson [12], Nguyen and Houlsby [13], Salari et al [14], Nguyen [15], Grassl and Jirásek [16]. A review of constitutive models based on damage mechanics and plasticity theory can be found in Nguyen [15].…”
