provided for the respective stress intensity factor K I . The formulae for k and K I can be easily applied by engineers in a wide range of geometries with edge discontinuities varying from almost semi-circular cavities to “mathematical” cracks, provided the length/depth of the notches remains short so as they do not affect each other. As a concluding remark, it should be mentioned that the procedure of introducing geometric discontinuities by means of “stress neutralization” of the respective regions of the body under study, may provide, also, the general solution for more complicated problems, as it is, for example, the configuration of a finite strip with mutually interacting edge notches, though in that case the solutions presented in Parts II and III need significant modifications.
