摘要: Abstract— In this paper the strain distribution and plastic zone size at a fatigue crack tip are discussed. From analysis considering critical condition for plastic-blunting, simple analytical formula calculating threshold stress intensity range propagation R= 0 is proposed. It found that calculated values in good agreement with existing experimental results.
