Paper Number: ARMA-2023-0355
... with the hydrate bearing sediments in the Shenhu area of the South China Sea. The stress-strain curve consists of three main phases, with strain softening occurring after initial plastic deformation. The cohesive force and internal friction angle correspond well to the actual hydrate bearing sediments by means...
