N2 - The Cohesive Crack Model (CCM) is the most commonly accepted discrete crack approach for modelling concrete based materials. It is applied to Ultra High Performance Fibre Reinforced Concrete (UHPFRC) in this study because it can be easily represented as cohesive interface elements (CIE) in finite element modelling (FEM). CCM using a bilinear traction-separation relationship is used to simulate the load-deflection behaviour of UHPFRC test specimens. CCM based numerical simulation of three-point bend specimens are implemented using cohesive elements in ABAQUS FE software. Progressive crack propagation and failure mechanism of UHPFRC test specimens are simulated in order to predict their load capacities.
