Numerical Analysis on the Softening Behavior of Concrete
초록
Ficticious Crack Model(FCM) is one of the Nonlinear Analysis Method which is presented strictly strain softening phenomena of concrete in the fracture zone. As no stress singularities occur, it is not necessary to use special crack tip elements for this analysis. A special feature of the used method is that it explains not only the growth of existing cracks, but also the formation of new crack, as it is assumed that cracks start forming when the tensile stress reaches ft, i, e the same criterion is used for formation and propagation of cracks.
