Evaluation of Stress Intensity Factors for an Electrostrictive Crack with an Electric Yielding Zone
전기적 항복영역을 갖는 전왜균열에 대한 응력강도계수 계산
Abstract
a crack with electrically impermeable surfaces in an electrostrictive material subjected to uniform electric loading is analysed. A strip yield zone model is employed to investigate the effect of electric yielding on stress intensity factor. complete forms of electric fields and elastic fields for the crack are derived by using complex function theory. /the stress intensity factors are obtained based on the strip yield zone model.
