Tension-Compression Damage Model with Consistent Crack Bandwidths for Concrete Materials

Figure 4

Comparison of estimations of crack bandwidth for a rectangular quadrilateral element: (a) geometrical meanings of crack bandwidths estimated by the present model, Oliver [56], and Govindjee et al. [58]; (b) large crack bandwidth estimated by the first method of Oliver [56]; (c) relations of tensile crack bandwidth and angle θ.
