共振声光谱在岩石、建筑材料和裂纹材料中的应用受到这些材料中大量机械损失和单个共振响应重叠的阻碍。本文描述了一种在存在强共振重叠的低q材料中测定共振频率的方法。实验研究了裂纹对共振频率和q因子值的影响。
The application of resonant acoustic spectroscopy to rock, building materials, and materials with cracks is hindered by the substantial mechanical losses in these materials and by the overlapping of the individual resonance responses. The paper describes a method for the determination of the resonance frequencies in low-Qmaterials in the presence of a strong overlapping of resonances. The effect of cracks on the values of the resonance frequencies andQfactors is studied experimentally.
