The <elastic> tag encloses a description of the constitutive relation of the intact elastic material and associated material properties, as may be selected from the list provided in Section 4.1.3↑ for unconstrained materials (used with “elastic damage”) and Section 4.1.2↑ for uncoupled materials (used with “uncoupled elastic damage”). The <damage> tag encloses a description of the cumulative distribution function and associated material properties, as may be selected from the list presented in Section 4.6.2↓. The <criterion> tag encloses a description of the damage criterion, as may be selected from the list presented in Section 4.6.3↓.
