摘要: This paper presents a comprehensive derivation of fracture process zone sizewhich closely parallels similar work in fracture of metals and anisotropic solids, but istheied to conrete. Some nonlinear mechanics models of concrete materials will bediscussed by using uniaxial stress assumptions. For uniaxial stress assertion, energymodel and fracture model will be presented for nonlinear softening models. Finally, wemake a compariSon with those models.
