First-principles calculations were used to estimate the anisotropic elastic and thermal properties of Ti2lnX (X = C, N) Zr2lnX M2AX phases. The crystals’ computed using Voigt-Reuss-Hill approximation. Firstly, material’s anisotropy was explored, its mechanical stability assessed. According findings, Ti2lnC, Ti2lnN, Zr2lnC, Zr2lnN are all brittle materials. Secondly, elasticity phase anisotropic...

The problem of propagation of plane wave including body and surface waves propagating in a transversely isotropic half-space with a depth-wise axis of material symmetry is investigated in details. Using the advantage of representation of displacement fields in terms of two complete scalar potential functions, the coupled equations of motion are uncoupled and reduced to two independent equations...

Effect of elastic anisotropy on indentation-induced thin film interfacial delamination, especially, at the initiation and early growth stage, is examined. The indentation load is modeled as a constant pressure over an expanding semi-spherical cavity. The delamination process is approached by a cohesive zone model. The rest of the problem is formulated within the general anisotropic elasticity t...

The anisotropic continuum stored energy density (ACSED) functional is applied for accurate constitutive modeling of biological tissues and finite element implementation without the isochoric—volumetric split, anisotropic—isotropic or invariant split. Related stress elasticity tensors in reference current configurations are worked out. A new kinematic model derived based on tangent Poisson’s rat...

One way to assess the validity of elasticity is with method atomic simulations. Molecular statics (MS) simulations are performed study interactions between H and edge dislocations in bcc iron using embedded-atom-method potential for a Fe-H system. The nature H-dislocation can be investigated examined. We show that sites strong binding energy found at dislocation core, as well slip plane, sugges...
