The dual boundary element method (DBEM) incorporated with fictitious crack model (FCM) is used to analyse and simulatethe crack propagation .in concrete. The fracture in concrete is represented by the FCM in which the fracture zone is replaced by applying closing forces on both crack surfaces. When the force at the ficti tious crack tip exceeds the maximum tensile strength of the concrete, the fictitious crack will propagate perpendicular to the maximum principal stress. Three-point bending specimen is used to check the numerical analysis and the res ults is compared to the analysis by finite element method and experimental results.
