Abstract
In the “Fictitious Crack Model” (1,2,3) the relation between deformation and stress is expressed by means of two curves, one stress-strain-curve and one stress-deformation curve. The stress-strain curve is valid for all of the material. The stress-deformation curve shows the relation between stress and the additional deformation of the fracture zone due to strain-localization. In the general case both these curves can be non-linear and comprise unloading branches. The curves are determined by means of tensile tests, and they are assumed to be material properties.
