Advanced Engineering Materials, EarlyView.Molecular dynamics is used to investigate structure refinement during severe plastic deformation. The results show similitude with experimental data. Molecular dynamics simulations of severe plastic deformation of monocrystalline and polycrystalline samples by multiaxial compression of aluminum are carried out.

Artificially cemented sand under multiaxial loading [PDF]
E3S Web of Conferences, 2019 Distinct improvement techniques can be used when civil engineering structures are to be built on soils that do not present suitable mechanical characteristics. The soil improvement techniques can vary from compaction to chemical and mechanical stabilisation. This work focuses on the specific case of granular soils treated with low amount of cement. The

Advanced Engineering Materials, EarlyView.This work studies the anisotropic behavior of circular notched tensile specimens of Ni‐base superalloy single crystals during high‐temperature tensile creep along [001], [110], and [111]. Correlative scale‐bridging imaging of specimens reveals early rupture along [110] because 1) plastic deformation proceeds faster at notch center; 2) more (brittle ...

Multiaxial fatigue of welded structures - Problems and present solutions
, 2022 S.3-15 (Vol.1)The assessment of multiaxial fatigue in design codes for welded steel structures is based on the use of nominal- or- hot-spot stresses, or by conventional hypotheses like von Mises, Tresca, principal stress or critical plane approaches ...

Design and Analysis of Compression–Torsion Coupling Metamaterials Using the Golden Section Method
Advanced Engineering Materials, EarlyView.A novel compression–torsion metamaterial is engineered using inclined rods and symmetry breaking. To optimize its torsional performance, the golden section method is employed. The mechanical response of the metamaterial is validated through both numerical analysis and experimental validation.

Proportional Loading Behaviour of Sand Under Multiaxial Stresses
Soils and Foundations, 1995 A study of sand deformation under proportional loading under generalized stress conditions is presented. The loading includes a variety of stress paths in which the principal axes of stresses have a constant inclination to the axes of the vertically water deposited specimens.

Advanced Engineering Materials, EarlyView.Functionally graded metal–ceramic femoral stems are engineered through continuous UMAT‐based stiffness tailoring, eliminating discrete material interfaces while enhancing biomechanical compatibility. Low‐index power‐law gradation optimizes load transfer, reduces stress shielding, and controls implant–bone micromotion, highlighting a materials‐design ...

Effects of Anisotropy and Multiaxial Loading on the Wrinkling of Sandwich Panels
Journal of Sandwich Structures & Materials, 2005 The works that have been already published on sandwich face wrinkling consider isotropic or almost isotropic sandwich configurations. Hence, only the critical wrinkling load needs to be evaluated in the principal compressive stress direction. This is insufficient for a sandwich panel with a higher degree of anisotropy.
