Showing all editions for 'Single crystal elastic constants and calculated aggregate properties' Sort by: Format; All Formats (17) Book (2) Print book (15) eBook (2) Single crystal elastic constants and calculated aggregate properties: a handbook Herbert Wang Print book: English. 2. ed: Cambridge, Mass.: M.I.T.P. 2. Single. Elastic properties of single cubic crystal can be described using three independent elastic moduli C11, C12 and C44,,. The calculated values (under 0 GPa) are listed in Table 2. It is easy to observe that C11 () is the largest value.

The elastic constants appearing in equation (1) are calculated by DFT and represent the elastic constants of a single crystal. While single-crystal elastic properties are important as input into higher length-scale modeling of mechanical behavior, we also derive and report several polycrystalline averaged properties.

Data on the elastic properties of single crystals has increased dramatically since Professor Simmons completed his first book in While this book is a consolidation of his earlier work, it has been extensively updated and revised to include new material and references, is far more complete, and is presented in a more useful form. This is actually a handbook consisting of computer printout. The elastic constants of zinc are compiled and reviewed; one hundred references are cited. The included elastic constants are: Young’s modulus, shear modulus, bulk modulus, compressibility, Poisson’s ratio, second‐order single‐crystal elastic stiffness and compliances, and third‐order, elastic stiffness. Temperature and elastic‐anisotropy effects are also reviewed.

waves are different in different directions and are determined by the elastic constants of the solid. The number of elastic constants, in the simplest case of an isotropic substance is two. In the most general case of a single crystal belonging to the triclinic system, the number required to describe the elastic properties completely is twenty-one.

We present an efficient method to obtain single-crystal elastic constants. Using the method, the computation effort for the complete set of elastic constants (21 components for a triclinic crystal) of a crystal under a given strain state is similar to that for the bulk modulus, where the latter is normally calculated first together with the equilibrium volume by fitting the volume-dependent.

If a single crystal of a metal is stressed in tension beyond its elastic limit, it elongates slightly and a step appears on the surface due to the relative displacement of one part of the crystal with respect to the others, and the elongation stops.

Further increase in the load causes movement of another parallel plane, resulting in another step. We have measured the shear modulus of lattices of charged polystyrene spheres.

We describe a simple apparatus used in this study for determining the frequency of standing shear modes. For the monodisperse lattices, crystals form, stabilized by the repulsive Coulomb interaction, producing a classical ’’Wigner crystal’’ characterized by Bragg scattering and finite rigidity.

The amount of clinopyroxene in upper-mantle pyrolite can be ∼15 vol%, while pyroxenite can contain as high as ∼60 vol% clinopyroxene.

Knowing the elastic properties of the upper-mantle diopside at high pressure-temperature conditions is essential for constraining the chemical composition and interpreting seismic observations of region.

The mechanical properties of a single crystal can be described as a deck of cards with bad glue between the cards. It is simple to shear the deck but it can take high compressive load.

For ice with many crystals (polycrystalline ice) the mechanical behaviour can be deduced from single crystal orientation. Atomistic simulations are capable of providing insights into physical mechanisms responsible for mechanical properties of the transition metal of Tantalum (Ta). By using molecular dynamics (MD) method, temperature and pressure dependences of the elastic properties of Ta single crystals are investigated through tensile loading.

First of all, a comparative study between two. An elastic modulus (also known as modulus of elasticity) is a quantity that measures an object or substance's resistance to being deformed elastically (i.e., non-permanently) when a stress is applied to it. The elastic modulus of an object is defined as the slope of its stress–strain curve in the elastic deformation region: A stiffer material will have a higher elastic modulus.

Elastic constants were determined for the nickel based alloy, Hastelloy X from room temperature to °C.
