TL;DR: In this article, a simple method using an optical camera in conjunction with an image processing tool is proposed to accurately measure the average strain experienced by rubbery polymers during a tensile test.

TL;DR: In this article, the constitutive parameters for a strain-rate and temperature-dependent Three Network (TN) material model were identified using the measured mechanical properties and the predictions were corroborated with measurements.

TL;DR: In this paper, carbon nanostructures, including both carbon nanotubes (CNTs) and graphene nanoplatelets (GNP), reinforcement of medical-grade polyetheretherketone (PEEK) and in-vitro bioactivity for biomedical structural applications were evaluated using 3D printed PEEK nanocomposites.

TL;DR: In this article, a class of soft color composites whose light transmittance can be actively tuned and controlled through mechanical actuation is studied, where thin sheets of polydimethylsiloxane, an optically clear silicone-based rubber, are mixed with a colloidal suspension of black micrometersized dye particles to provide tunable opacity to the specimens.

TL;DR: In this article, a theoretical framework is presented for the stress analysis of shaft-tube adhesive joints subjected to axial tensile loads, where the axisymmetric assembly consists of similar or dissimilar isotropic or orthotropic adherends and a homogeneous adhesive layer.
