| Abstract: | in this paper. the fundamental equtions for the vibration problem of the quadrilateral sheet metal in the transverse magnetic field are obtained. The vibration speciality of a quadrilateral sheet metal simply supported along four sides is investigated. By using a numerical method. the effect of change in magnetic field upon vibration frequency and attenuation coefficient is shown. |
