Measurement of Complex Modulus and Parameters of Viscoelastic Materials by Means of Vibrating Beam
用振动梁方法测量粘弹性材料的复模量和粘弹性参数

The complex modulus and three viscoelastic parameters of standard linear model of solid are obtained by measuring the response, phase retardation at a point on beam vibrating at resonant frequency. It is shown that this method is simple, reliable and practically applicable.
