Numerical Study on the Rebound of Low-Velocity Impact-Induced Indentation in Composite Laminate
Aerospace, 2022 Indentation is an effective indication of LVI damage in PMCs. However, indentation can rebound partly with time. Thus, a good understanding of the rebound behavior of the impacted pit is helpful in damage assessment for composites.

Advanced Engineering Materials, EarlyView.This study proposes a potential device design for joint cartilage replacement. Silica‐polytetrahydrofuran (SiO2‐PolyTHF) hybrids with customizable mechanical properties were developed to mimic the characteristics of a natural meniscus. These were synthesized through a two‐pot sol–gel hybrid process.

Advanced Engineering Materials, EarlyView.A high interstital austenitic steel is additively manufactured and postdensified by HIP to eliminate gas porosity. Thereby, the loss of N and Mn in Ar HIP atmosphere is investigated. Further, HIP using N2 atmosphere is investigated which led to excessive nitride formation.

LOCAL NANO-MECHANICAL PROPERTIES OF CROSS-LINKED POLYBUTYLENE
Acta Polytechnica CTU Proceedings, 2020 Cross-linking is a process in which polymer chains are associated through chemical bonds. The cross-linking level can be adjusted by the irradiation dosage and often by means of a cross-linking booster. The polymer additional cross-linking influences the

Advanced Engineering Materials, EarlyView.A thermoplastic PMMA‐based photoresin enables high‐resolution DLP printing followed by solvent‐vapor smoothing. The treatment reduces staircase‐induced surface roughness from 2.33 µm to 129 nm and increases visible‐light transmittance from approximately 30% to 80%, providing a route toward transparent PMMA components for rapid prototyping and non ...

Small depth indentation of plastic materials
Polymer Testing, 1994 Abstract A new apparatus was developed to perform creep, recovery, relaxation or indentation tests based on the local deformation of polymeric solids by harder indenters. This paper outlines the design concepts of this device that fits in a typical universal tensile testing machine.
