Experimental Study on Viscoelastic Behavior of Sedimentary Rock under Dynamic Loading

Rocks with micro defects do not always behave elastically but sometimes viscoelastically under dynamic loading. Attenuation and dissipation occur when stress wave propagates through an intact rock with micro defects, which cannot be described using traditional elastic rock models. A proper viscoelas...

Description
Summary:Rocks with micro defects do not always behave elastically but sometimes viscoelastically under dynamic loading. Attenuation and dissipation occur when stress wave propagates through an intact rock with micro defects, which cannot be described using traditional elastic rock models. A proper viscoelastic model of rocks is thus important once the stress wave propagation caused by earthquakes, blast, and impact forces is under concern.
