Quantitative calculation for the dissipated energy of fault rock burst based on gradient-dependent plasticityXuebin Wang;Shuhong Dai;Long Hai Department of Mechanics and Engineering Sciences, Liaoning Technical University, Fuxin 123000, China摘 要:<正> The capacity of energy absorption by fault bands after rock burst was calculated quantitatively......
energy loss, presenting a low absorption coefficient. The high frequency waves, with large amplitude, will generate a non-elastic collision, and a high absorption coefficient can be expected. A good... sound wave in the structure to consume a lot of sound energy [26]. The sound absorption effect would become better with air gap behind the porous material. Viscous loss and heat loss are two main......
