Finite element modeling of crack propagation in RC beam by using energy approach
In present study interface element with nonlinear spring is used to simulate cohesive zone model (CZM) in reinforced
concrete beam in Mod I of crack propagation. Modified crack closure integral method is implemented to model
propagation of fracture process zone (FPZ). This model, energy can calculate energy release rate in concrete by using
new method in energy approach. Energy dissipation rate by steel bars is obtained to affect on crack propagation criterion
to implement in finite element method. The results show that proposed model does not depend on mesh size
