Fretting fatigue crack propagation rate under variable loading conditions

Fracture and Structural Integrity, 2015
Fretting fatigue experiments aim to represent industrial problems and most of them endure variable loading. Being able to assess lifetime of assemblies, especially for low propagation rate conditions, is essential as experimental validation is often too ...

Enhanced Infection Resistance and Regenerative Healing of Titanium Implants via Peptide‐Loaded Biodegradable Coatings

Advanced Materials Technologies, EarlyView.
This study presents a new biodegradable coating for titanium implants using a natural antimicrobial peptide, caerin 1.9. Applied via solvent casting, the coating offers sustained antibacterial protection and promotes healing. Tested on 3D‐printed porous titanium scaffolds, it effectively prevented infection—including against resistant bacteria—while ...

Implementation of a Two-Dimensional Finite-Element Fatigue Damage Model with Peridynamics to Simulate Crack Growth in a Compact Tension Specimen

Applied Sciences
The traditional finite element method (FEM) has limitations in accurately modeling crack propagation. Peridynamics, a nonlocal extension of the classical continuum theory, provides an alternative approach to remedy the limitations of the FEM but with a ...

Influence of steam sterilization on the mechanical and low-cycle fatigue properties of polyetheretherketone parts obtained by material extrusion additive manufacturing technology

Materials & Design
Steam sterilization is a mandatory post-processing step for polymer-based medical implants; however, its influence on fatigue damage evolution in additively manufactured high-performance polymers remains insufficiently understood.
