Other AbstractAn experimental investigation of arresting crack propagation by pulse discharging to a 45# steel plate with crack was shown herein.Through the microstructure analysis near crack tip after crack prevention by using electromagnetic heating effect,it is found that the phase transformation has been occurred.Also,the residual strain of phase transformation near crack tip has gotten by X-ray diffusion method.The theoretical calculation of the phase transformation stress was finished by Eshelby’s model of imaginary cutting method.The affection of the residual stress on the crack propagation was discussed.It is found that the residual stress will have a long term effect for crack prevention.The results obtained show that the technique of arresting crack propagation by using electric magnetic heat effect has both academic feasibility and practicability.
