THEORETICAL ASPECTS OF CRACK GENERATION AND GROWTH

A review of the initiation and growth of cracks is given, starting with the work of Griffiths А. and ending with the work of Foreman R.J., Maimon G. and Kassim S. The use of classical formulas for determining the growth rate of fatigue cracks, such as the Paris formula, does not allow taking into account the diversity and complexity of loaded bodies, sizes and shapes of cracks. It is shown that in order to obtain the crack growth rate equation, it is necessary to use the catastrophe theory with suitable control parameter
