Frequency of arboreality is correlated with longer hand skeletons in Gorilla: Analysis of a new skeletal sample of Bwindi mountain gorillas

Journal of Anatomy, EarlyView.
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,

A NEW MULTIAXIAL FATIGUE LIFE PREDICTION MODEL AND ITS APPLICATION (MT)

Jixie qiangdu, 2023
When mechanical components are subjected to multiaxial cyclic loading during operation, the additional strengthening effect is easy to occur. Using uniaxial fatigue life calculation formula to predict their life will produce large errors.

Investigating Crack Resistance Behavior of Polypropylene Using J integral, J‐R Curve and Fractographic Analysis

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 8, Page 3404-3419, August 2026.
ABSTRACT In this study, the fracture response of polypropylene (PP) was assessed using J‐integral evaluation, J‐R curve construction, and fractography examination. J‐R and load–displacement curves were analyzed to determine critical loads and estimate J‐integral values based on standards established for polymer fracture testing, which led to the ...

Comparison of pedicle screw loosening under uniaxial and multiaxial loading

Clinical Biomechanics
Pedicle screw loosening is a clinically-relevant failure mode following spinal fusion procedures, resulting from damage and compaction to the surrounding bone with loading of the bone-implant interface. Current in vitro tests for investigating pedicle screw loosening commonly apply uniaxial loading (e.g. screw pullout or toggle testing). However, these

Predicting Crack Propagation in Brittle TPMS Under Uniaxial Loading: A Dual Concept Approach via Geodesic Lines and Cross‐Sectional Analysis

International Journal of Ceramic Engineering &Science, Volume 8, Issue 4, July 2026.
Cracking in brittle TPMS structures is governed by their geometry, with cracks propagating along geodesic paths determined by the initial crack orientation. Regions with small cross‐sections and abrupt area transitions identify critical damage regions and explain the differences in compressive strength among Primitive, Gyroid, Neovius, and IWP designs.

Multiaxial Fatigue Behavior of AA6016 and AA6016 to DX54D SPR Joints: Fracture Mechanisms and Data‐Driven Rupp's Model

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 7, Page 2929-2944, July 2026.
ABSTRACT The fatigue and fracture behavior of self‐piercing rivet (SPR) joints between AA6016 aluminum sheets (1–2 mm) and DX54D steel (0.95 mm) was studied under 90°, 45°, and 0° multiaxial loading. Pure shear (90°) loading produced the highest fatigue strength, whereas multiaxial (45°) loading resulted in reduced performance, with pure tension (0 ...

A novel approach to simulate the stiffness behaviour of spot welded vehicle structures under multi axial variable amplitude loading

MATEC Web of Conferences, 2018
Under cyclic loading in combination with high local stress levels a change in stiffness of connection points, e.g. spot welds, self-piercing rivets or flow drill screws can be observed.
