The Dugdale traction law was implemented within a finite volume code in order to simulate the binder course mortar material response when subjected to indirect tensile loading. A uniaxial tensile test and a threepoint bend test were employed to determine initial stress-strain curves at different test rates and the cohesive zone parameters (specifically, fracture energy and cohesive strength). Numerical results agree well with the experimental data up to the peak load and onset of fracture, demonstrating the value of the cohesive zone modelling technique in successfully predicting fracture initiation and maximum material strength.||Funding Details:||Other funder||Type of material:||Journal Article||Publisher:||Elsevier||Copyright (published version):||2010 Elsevier Ltd.||Keywords:||Binder course mortar;Finite volume method;Indirect tensile loading;Three-point bend test||Subject LCSH:||Mortar--Testing
