Original Abstract

The maximum tangential stress (MTS) criterion is traditionally used for evaluation of fracture resistance curve and crack initiation angle under mixed mode I/II. In the application of MTS criterion, values of stress intensity factors (SIF) for mode I and II are used. However, the concrete materials consist of matrix and various aggregate sizes, the aggregate size could have influence on the crack initiation angle under the mixed mode I/II. In this paper, a generalized maximum tangential stress (GMTS) criterion is used to investigate the influence of selection of critical distance on the crack initiation angle for concrete C 50/60. Various critical radiuses are investigated (the lengths are selected based on the size of the process zone and on the maximum size of coarse and fine aggregate). The numerically obtained results are discussed and compared with experimental results. The predicted results of GMTS criterion for a suitably chosen distance in different mixed mode conditions show good agreement with the available experimental ones.
