...Yupeng Zhang; Zdeněk P. Bažant The crack band model, which was shown to provide a superior computational representation of fracture of quasibrittle materials (in this journal, May 2022), still suffers from three limitations: (1) The material damage is forced to be uniform across a one-element wide...

... model M7 for concrete [ 31 ] has been used as the damage constitutive equation (the other curves are explained later). Fig. 2 ( a ) Schematic of microcracks in the fracture process zone and how its size evolves with σ xx in quasibrittle materials: strengthening G f —0 < σ xx...
