a constitutive model based on two–dimensional unstructured galerkin finite volume method (gfvm) is introduced and applied for analyzing nonlinear behavior of cracked concrete structures in equilibrium condition. the developed iterative solver treats concrete as an orthotropic nonlinear material and considers the softening and hardening behavior of concrete under compression and tension by using...

Many infrastructure objects made from concrete like bridges are in bad condition. Different types of damage corrosion and fractures reduce the stiffness strength significantly. Knowledge fracture propagation is essential to predict remaining life time guarantee a safe operation. There different approaches solve this problem. On one hand finite element simulations including cohesive zone modelin...
