Analysis of weak magnetic nondestructive testing for cracks in the top beam of hydraulic support
In view of the complicated operation of the current crack detection method of hydraulic support, a weak magnetic nondestructive detection method for cracks in the top beam of hydraulic support based on geomagnetic field excitation is proposed. Firstly, the stress field of the crack in the top beam o...
