“…Therefore, during the deformation process only the amount of the damage increase (void growth) can be modelled, regardless of the change in void shape accompanying this growth. Several models that take into account damage anisotropy in metallic materials using CDM approach are available in the literature (Abu Al-Rub and Voyiadjis, 2003; Benzerga and Leblond, 2010; Besson, 2009; Chow and Jie, 2008; Desmorat, 2009; Garion and Skoczen, 2003; Murakami, 1990; Rajhi et al., 2014) However, for polymeric materials, damage anisotropy is mainly described using the PP approach (Benzerga et al., 2004; Besson, 2009; Chung et al., 2013; Gologanu et al., 1993, 1994; Zaïri et al., 2011).…”
