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, EarlyView.
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 ...

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,

Capturing Complex Rate‐Dependent Behaviors of Saturated Clays: A Fractional Consistency Kinematic Hardening Viscoplastic Approach

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 8, Page 3281-3296, 10 June 2026.
ABSTRACT Saturated high plasticity clays show complex nonlinear, rate‐dependent, and hysteresis behaviors under non‐monotonic stress paths, requiring advanced mathematical constitutive equations for accurate description. Taking into account the inherent advantages of kinematic hardening mechanisms in simulating complex stress histories, this paper ...

Efficiency Enhancement Strategies on the Concept of Representative Directions Applied to the Dynamic Flocculation Model for Filled Elastomers

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT The physically‐motivated dynamic flocculation model (DFM) is capable of modeling the non‐linear material behavior of filled elastomers, for example, as damping elements in centrifuges. For predicting the system behavior of these dynamic systems, it is planned to incorporate DFM into a multi body simulation (MBS) framework.

Hybrid Data‐Driven and Physics‐Informed Learning of Cyclic Plasticity For Pipe Steel

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT An efficient and explainable machine learning (ML) approach is presented, replacing conventional material models based on the radial return mapping (RRM) algorithm for the constitutive modeling of cyclic plasticity in 3D. The application of transfer learning, based on an existing model for a separate class of steel, leads to a significant ...

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

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.
