Wedge-Splitting Test ? Determination of Minimal Starting Notch Length for Various Cement Based Composites. Part I: Cohesive Crack Modelling

Original language description

The geometric proportions of cube-shaped specimens subjected to wedge-splitting tests are numerically studied in the paper. The minimal notch length for specimens made of cement based composites varying in characteristic length of the material (a measureof material brittleness/ heterogeneity) is verified using finite element method code with an implemented cohesive crack model (ATENA). The problem of assigning the crack initiation point (the notch tip vs. the groove corner in the load-imposing area ofthe specimen) is solved numerically also usány both the theory of linear elastic fracture mechanics and the theory of the fracture mechanics of generalized singular stress concentrators in the second part of the two-part paper. Results obtained by the different approaches are compared. The minimal notch length is recommended
