✦ Synopsis
The problem of notch sensitivity of concrete is discussed with the influence of size effect taken into account. The need to consider the size effect on the tensile strength of concrete was noted. It is shown that the critical stress intensity factor, KIC, is connected with the tensile strength of the material, which gives an opportunity to estimate the Kic-value on the results of standard strength tests of the unnotched specimens. In conclusion, a practical condition for quasi-brittle manner of failure has been found.
