Abstract:Alternating current field Measurement is one of the important progresses about electromagnetic nondestructive testing in recent years. Alternating magnetic fields excitation testing model is established by using electromagnetic simulation software ANSOFT, a flat plate crack defects are simulated. By analyzing its principle, crack depth and the width change influence on test results, finally the simulation results are verified by the method of experiment. The experimental results are consistent with the simulat… Show more
