Piezoresistive Monitoring of Carbon Nanomaterial‐Reinforced Epoxy Composites Under Cyclic and Fatigue Loading: A Review

open access: yesAdvanced Engineering Materials, EarlyView.
Carbon nanomaterial‐reinforced epoxy composites exhibit pronounced piezoresistive behavior, enabling intrinsic damage sensing under cyclic and fatigue loading. This review critically compares carbon nanotube and graphene systems, correlating filler content, percolation threshold, and gauge factor with sensing stability and damage evolution.

Axial-torsional fatigue of pultruded glass-fiber tubes

open access: yesResults in Engineering
Fatigue characteristics of the pultruded glass-fiber composites were extensively investigated experimentally. Tubular specimens with three-layer structure (mat, roving, mat) were subjected to simultaneous cyclic axial and torsional loads to initiate ...

Multiaxial elastic-viscoplastic stress analysis of composites

open access: yesComposites Part C: Open Access, 2020
Theoretical predictions of time-dependent deformation and damage response of metal matrix composites under multiaxial stress states are presented. The predictions are made using a finite element analysis method that incorporates an inelastic deformation and damage theory for composites.

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

open access: yesAdvanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

A fast algorithm to racetrack filter multiaxial histories preserving load shape [PDF]

open access: yesMATEC Web of Conferences, 2019
A fast algorithm is presented to implement a multiaxial version of the racetrack amplitude filter, improved upon the authors’ previous works. The algorithm only requires a single user-defined scalar filter amplitude to eliminate noise and potentially non-

From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

open access: yesAdvanced Functional Materials, EarlyView.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.
