The aim of the paper is twofold: Firstly, to demonstrate the necessary correspondence between the experimental MCT test setup and finite element simulations and secondly, to initiate the way of establishing the desirable conversion between the fracture energy parameter values resulting from the MCT test and the standard conventional procedures. MCT tests are carried out and compared with the numerical results from 2-D and 3-D finite element calculations using the commercial codes<br>ABAQUS and ATENA, the latter being specifically developed for applications on concrete structures and<br>elements. In this way, the usability of the modified compact tension test for practical purposes is confirmed.</p> ER -
