Strain Rate-Dependent Mechanical Response of Hydrate-Bearing Sediments under Plane Strain Condition

Natural gas hydrate has gained significant attention in recent years. To safely and sustainably exploit the natural from hydrate-bearing sediments, it is crucial to understand long-term mechanical characteristics of reservoir. In this study, influence fine particles on strain rate dependence sediments under plane conditions been studied. The experimental results show that dependency properties positively correlated with saturation instead morphology sediments. residual strength primarily controlled by independent rate. Changes fines content can affect relationship between shear band angle. Finally, local volumetric expansion effect without more shows a strong characteristic. Overall, study provides valuable insights into reservoirs. These contribute development constitutive model time future, which meaningful exploitation hydrate.
