摘要
Abstract
This paper proposed a method resulting from electromagnetic properties variation for metal plastic deformation monitoring.Firstly,the influences of electromagnetic parameters (permea-bility,conductivity)on the radio-frequency reflection features of the metal plate samples were simula-ted.Energy distribution of radio-frequency varies obviously due to electromagnetic properties variation according to the simulation results.Experiments were conducted to verify simulation results.The re-sults of the experiments indicate that the reflected radio-frequency signal strength decreases with pro-gressive plastic deformation in metal,which has been in conformity with simulations.关键词
