Elastic modulus encompasses various types of moduli that describe material stiffness under different kinds of deformation, such as shear or bulk compression. Young's modulus, a specific type of elastic modulus, is focused on uniaxial tension and compression, providing insight into a material's ability...

For larger alloying, phase and particle or fiber additions (as in composites) the modulus value is generally given by a complex weighted average of the moduli for individual constituents. The magnitude of the modulus is largest at the lowest temperatures. As the temperature increases, E falls ...

The post-stishovite transition is a classic pseudo-proper typed ferroelastic transition with a symmetry-breaking spontaneous strain. This transition has been studied using high-pressure spontaneous strains, optic modes, and elastic moduli (Cij) based on the Landau modeling, but its atomistic informatio...
To illustrate both our GBM-Locfit approach and the use of descriptor candidates constructed as Hölder means, we predict the elastic bulk and shear moduli (K and G, respectively) of k-nary inorganic polycrystalline compounds. These moduli govern the stress-strain relations of isotropic materials ...

It is evident that the dynamically evaluated Young's modulus yields results in good accordance with the evaluated moduli from curvature, as well as literature values, which range from 169 GPa for the 〈110〉 direction to 130 GPa for the 〈001〉 direction [38]. Eslope underestimates the ...
