Human In Vivo Disc Mechanics in Flexion, Extension, and Diurnal Loading With Aging and Degeneration
JOR SPINE, Volume 9, Issue 3, September 2026.ABSTRACT Background The intervertebral disc serves a critical role in spine function, but with aging and degeneration the disc undergoes changes that alter disc mechanics, and degeneration is often implicated in low back pain. The objective of this study was to quantify and evaluate the impact of aging and degeneration on in vivo lumbar disc mechanics ...

Fatigue Crack Modeling of Railheads Using a Nonlinear Cohesive Zone Model
Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 9, Page 3738-3750, September 2026.ABSTRACT Subsurface fatigue crack growth within railheads can be deleterious leading to catastrophic failures in rails. This study aims to model the fatigue crack growth originating at the subsurface level within railheads. Towards that end, a finite element modeling approach is utilized wherein complex crack growth is explicitly modeled using a ...

Journal of Anatomy, Volume 249, Issue 3, Page 457-475, September 2026.We review the characteristic changes to the limb soft tissue and neurovascular abnormalities that have been described in the congenital limb birth defect, Radial Dysplasia. These include consistent changes in muscle anatomy or absence of specific muscles, persistent median arteries and absent radial arteries and consistent alterations in neural ...

Journal of Anatomy, Volume 249, Issue 3, Page 544-564, September 2026.Variation in arboreality across gorilla populations is associated with systematic differences in manual digital lengths. Using a new dataset of linear metrics from the Bwindi mountain gorillas, we quantify metacarpal and phalangeal lengths in eastern and western gorilla populations across all five rays. Consistent with quantified behavioral differences,

Design and Analysis of Compression–Torsion Coupling Metamaterials Using the Golden Section Method
Advanced Engineering Materials, Volume 28, Issue 16, 19 August 2026.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.

Soft Mechanical‐Electrical Logic Using Liquid Metal‐Filled 3D‐Printed Architectures
Advanced Engineering Materials, Volume 28, Issue 15, 5 August 2026.We present 3D‐printed soft mechanical–electrical logic elements that use liquid metal–filled silicone tubes actuated by thermoplastic polyurethane/polylactic acid (TPU/PLA) architectures to produce Boolean operations. Complementary normally open and normally closed unit cells perform repeatable binary transitions and can be combined into more complex ...

Advanced Engineering Materials, Volume 28, Issue 15, 5 August 2026.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.

Advanced Materials, Volume 38, Issue 48, 26 August 2026.Field‐programmed anisotropy imparts material‐level intelligence to soft composites. Magnetic torque dynamics drive magneto‐piezoelectric nanowires from random dispersion into deterministic axial alignment. The resulting hierarchical percolation networks confine electromechanical coupling to specific axes and intrinsically decouple superposed force ...
