Research on damage viscoelastic dynamic constitutive model of granite
Dynamic mechanical properties of granite were tested by a split Hopkinson pressure bar system with constant strain rate.The initial loading stage of stress-strain curve of granite is linear elasticity, and the rock material has a significant plastic deformation after yielding.Yield strength, peak st...
