Stress Wave Attenuation in Isotropic Damaged Rocks

CUI Xin zhuang 1,LI Wei min 2,DUAN Zhu ping 1, CHEN Shi hai 3(1.Institute of Mechanics,the Chinese Academy of Science,Beijing 100080,China;2.The Second Filial of Constructive Ltd Co.of Shandong Province,Jinan 250014,Shandong,China; 3.Shandong U  
An expression for stress wave attenuation rate was derived based on one dimensional wave propagation and interaction in samples between Hopkinson bars.The relation between attenuation rate and initial damage was studied experimentally on damaged rocks.Also the attenuation rules of spherical and cylindrical explosive stress waevs are derived based on stress equivalent method.
