WebAbstract: Crack propagation is one of the key issues for simulating nonlinear behavior and evaluating safety of concrete structures. The equivalent crack opening displacement of smeared damage-fracture model is formulated with damage parameter and crack band width. Mode I and mixed-mode fracture tests of concrete beams are analyzed using … Webmodel for the non-linear response when the principal stresses are dominantly compressive. In tension (including tension-compression zone), cracking is assumed to occur when the stress reaches a failure surface which is called the “crack detection’ surface.
