Indentation Creep and Relaxation Measurements of Polymers

, 2004
Instrumented indentation was used to characterize the mechanical response of polymeric materials. A model based on contact between a rigid probe and a linear viscoelastic material was used to calculate values for creep compliance and stress relaxation ...

Long‐Term Hydrophilic, Anti‐Clotting, and Anti‐Fibrotic Dynamic Covalent Silicone‐Based Biomaterials

Advanced Healthcare Materials, EarlyView.
Dynamic covalent crosslinking of a Schiff‐base silicone elastomer with hydrazide‐functionalized polymers is demonstrated to improve the long‐term hydrophilicity as well as the anti‐fouling and anti‐clotting properties of PDMS implants. The hydrazone‐functionalized material prevents hydrophobic recovery, resists clotting, and significantly reduces ...

Creep of Amalgam at Low Stresses

, 1987
The creep and recovery, of dental amalgam were studied with a torsional creep apparatus. The purpose was to investigate viscoelastic behavior in a low stress range that might result from normal chewing forces. The creep of specimens up to six months old

Laboratory Evaluation of Tensile Creep Behavior of Concrete at Early Ages

Applied Sciences
Short-term uniaxial tensile creep tests were conducted for early-age concrete at different ages in an effort to characterize early-age concrete as an aging viscoelastic material. Based on the test results, the viscoelastic material properties of the test

Standardized Effect Measures Informing Next‐Generation Strategies for Mechanical Stimulation in Cartilage Tissue Engineering

Advanced Healthcare Materials, EarlyView.
This systematic review quantitatively compares conventional mechanical stimulation strategies in cartilage tissue engineering across 85 heterogeneous in vitro studies. Applying standardized effect measures, meta‐analysis reveals that combined compression and shear loading optimally promotes cartilage matrix development.

Atomic Layer Deposition Processes: Versatile Platforms for Engineering ZnO‐Chitosan Biointerfaces

Advanced Healthcare Materials, EarlyView.
Vapour phase metalation (VPM), multiplied pulsed vapour phase infiltration (MPI), and O2 plasma‑enhanced atomic layer deposition (PEALD) tailor Zn–chitosan (Zn‑CS) films. PEALD improves wettability and biocompatibility. MPI enhances semiconductor behavior. Antiseptic selectivity: VPM → E. coli; MPI → H. pylori.

A comprehensive evaluation of transient-test-based approaches for determining creep function in heterogeneous polymer pipes

Applied Water Science
Determining the creep function of polymer pipes is the primary problem in predicting their reaction to abrupt loads, such as transient flow. This study analyzes transient pressure data’s time and frequency domains to evaluate the pipe wall creep function.
