In this paper, the S-theory is applied to determine crack initiation and direction for Tbeams.
It makes use of a parameter called strain-energy-density factor, S, which is a
function of the stress intensity factors. A simple method for obtaining approximate
stress intensity factors is also applied. It takes into account the elastic crack tip stress
singularity while using the elementary beam theory. Basic loading conditions are
