Simulation‐Based Analysis of Insert Pull‐Out in Nickel‐Polyurethane Hybrid Foams Using CT‐Derived Geometries

open access: yesAdvanced Engineering Materials, Volume 28, Issue 21, 4 November 2026.
CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.

When Teeth Twist: Distinct Mechanisms and Patterns of Enamel Wear from Rotational Forces—A Preliminary Investigation

open access: yesAmerican Journal of Biological Anthropology, Volume 191, Issue 3, November 2026.
ABSTRACT Motivation Dental enamel possesses a unique anisotropic, heterogeneous hierarchical structure which enables a combination of high hardness and remarkable durability compared to other natural and synthetic biomaterials. Nevertheless, it undergoes mechanical degradation through fracture from concentrated overloads and/or progressive wear, both ...

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3036-3076, November 2026.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Polyglycine Strands Within a Collagen Triple Helix

open access: yesBiopolymers, Volume 117, Issue 6, November 2026.
ABSTRACT The collagen triple helix is the most abundant protein structural motif in animals. It tolerates any amino acid in its Xaa and Yaa positions but demands glycine (Gly) at every third position, where the residue packs into the sterically forbidding core of the triple helix and donates the recurring interstrand N–H⋯OC hydrogen bond that stitches

Numerical and Experimental Evaluation of a Simplified Lateral Spring Formulation for Rocking Structures

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 14, Page 3540-3560, November 2026.
ABSTRACT Rocking podium isolation systems have gained significant research interest as a method of limiting seismic demands on superstructures and eliminating residual post‐earthquake drifts through self‐centring behaviour. However, while numerous models of varying complexity, including analytical, phenomenological, and physical formulations, have been
