“…In the crack band approach, as strain localizes in one element, the finite element size h needs to be proportional to w t by a readily determined proportional constant (e.g. w t ¼ ffiffiffiffiffiffi 2A p for a linear element, with A being the area of the element; in Rots (1988), Feenstra and de Borst (1995)). Otherwise, the stress-strain softening curve of the local constitutive model must be adjusted to assure the right amount of dissipation specified by the fracture energy G F (Bazant and Oh, 1983;Bazant and Cedolin, 1991 (Chapter 13)).…”

“…It is noted that a descending branch also arises in tension-stiffening models and rational ways to separate the tension-softening and tension-stiffening effects in reinforced concrete have only been proposed in the mid 1990s (Feenstra, De Borst, 1995). Also this issue is still partly open.…”

“…Assim, diversas leis constitutivas para simular a interface aço-concreto têm sido desenvolvidas utilizando diagramas de comportamento bilinear ou trilinear associados a elementos uniaxiais, biaxiais e triaxiais (Désir et al, 1999;Kwak & Kim, 2001;Salari & Spacone, 2001;Kwak & Filippou, 1997;Yankelevsky, 1997;Bangash, 1989;Abrishami & Mitchell, 1996;Feenstra & De Borst, 1995).…”
