Elastic constantsPressure derivatives of bulk modulus and elastic constants71.15.Dx71.15.NcWe investigate the maximum likelihood metameres of local pure 2 nd order structure in natural images. Using the shape index, we re-parameterise the 2 nd order structure and gain a one-parameter index which ...
The stiffness of an isotropic elastic material can be described by two moduli, i.e. the bulk modulus K and shear modulus G. To design the stiffest cellular material, the optimization problem can be described as properly distributing the solid material within PBC subject to a given material volu...
Willis coupling is a term in the acoustic and elastic constitutive relations that couples potential and kinetic energy11,12,13, analogous to the bianisotropy parameter in electromagnetism14,15. The Willis coupling and bianisotropy parameters can only be non-zero in structures with low symmetry16, ...
(12A) Material parameters. Rhenium has been of particular interest due to its large bulk modulus (K), shear modulus (G), and high strength16,30. The following properties of rhenium are used in simulations: Elastic constants8,16,30 λe = 247 GPa, G = 200 GPa, l = − 291 GPa,...

6.12. Assuming that the rock behaves like elastic and isotropic material and no fluid penetrates into the fracture, Haimson and Fairhurst (1967) derived the following equation to calculate the fracture initiation pressure that can be used for the leak-off test analysis in a vertical well, and ...
Mechanical properties, such as yield point and elastic modulus (expressed in terms of Poisson's ratio), were determined using a 1 4 in dia plunger with a compression testing device. The differences between the 40°F properties and those at 90°F were noted. These differences were used to ...
