... by loading and unloading procedure was applied on the inner surface of casing. Radial and hoop stress were analyzed to determine the formation of failure. Plastic strain was shown to illustrate the plastic deformation within the cement sheath. The results showed ductile cement had better performance than...

... induced by NFs, and the isotropic model, which ignores both the fracture induced anisotropy and the lamination induced anisotropy, are applied to the same synthetic OB rock to interpret the stiffness coefficients, Young's modulus, Poisson's ratio, minimum horizontal stress, min/max hoop stresses...
