Fig. 2. An example of the FE mesh and displacement boundary conditions; critical radial distance is marked.

Young’s modulus and Poisson’s ratio were assumed 210 GPa and 0.3 for the steel anchor and 23.5 GPa and 0.2 for concrete, respectively (note that using the linear elastic material model for concrete is not unusual in pilot research studies to obtain basic information about the qualitative nature of results obtained at the beginning of the analysis). The analysis is based on investigation of the tangential stress distribution around the anchor’s corner; particularly several critical distances of 1, 2, 3, 4 and 5 mm were considered in agreement with the theory of critical
