The discussion on the Young´s modulus measurement of biological electret-bone by cross-sympathetic vibration method

Dynamic experiment method is an efficient tool to measure modulus of elasticity in mechanical study and analysis. In this work we obtain the modulus of elasticity of biological electret bone with the cross-sympathetic vibration, and the proof is done by static method (laser speckle method). The outcome proves similar Young\´s modulus using the two methods. The result is stable with little error, and it is easy to obtain plenty of valuable data in short time, moreover, we analyze the sample\´s modulus of elasticity in different temperature. All this is useful to explore the characteristic of the" force to electricity" of skeleton as a typical biological electret.
