Material Selection and Geometric Design for Few‐filament Shape Memory Polymer Yarns for Force Generation

Advanced Materials Technologies, Volume 11, Issue 13, 8 July 2026.
A custom shape memory polymer material selection process relates quantitative application criteria (e.g., compression garment yarns) to material characterization information. The selected materials are manufactured into yarn geometries, which expand the design space by creating structural stress‐strain profiles beyond the nominal material stress‐strain

Current‐Generation Crosslinked Polyethylenes for Total Hip Arthroplasty: Mechanistic Insights Into Oxidative Stability and Antioxidant Efficiency

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 7, July 2026.
ABSTRACT Highly crosslinked polyethylene (XLPE) has revolutionized total hip arthroplasty (THA), but increased radiation doses and complex crosslink structures may increase oxidation susceptibility. The long‐term oxidative stability of XLPE depends on manufacturing factors, including crosslink density, antioxidant (vitamin E) concentration ...

Characterization of the Fatigue Threshold Behavior of Uhmwpe

Journal of the Mechanical Behavior of Biomedical Materials
Ultra-high-molecular-weight-polyethylene (UHMWPE) has been the material of choice for bearings in total joint replacements (TJRs) for decades as a result of its excellent wear resistance, chemical inertness, energetic toughness, low friction, and biocompatibility.
