Induced Damping And Its Relationship To Beneficial Energy Harvesting In Dielectric Elastomers With Application To Walking
… of composite electrode/DE polymers under uniaxial stretching and electrical loading by improved hyperelastic modeling and experiments; (2) development of relationships between energy harvesting and damping for the DE materials in uniaxial stretching and on a biofidelic knee model; and (3) …

Structural and mechanical analysis of the black widow spider web subjected to stretching, expansion and wind
… widow) is tested under three loading conditions: uniaxial stretching, expansion in the three main directions and shearing effects of the wind action. In addition, to determine whether the response of the erratic ensemble of threads is efficient as compared to a more orderly system, a second …

Investigations of the Processing-Structure-Property Relationships of Selected Semicrystalline Polymers
… out on a three stage method (extrusion/annealing/uniaxial-stretching) (MEAUS) utilized to produce semicrystalline polymeric microporous membranes. The two semicrystalline polymers studied were selected based on a set-of-prerequisites proposed for the formation of highly porous membranes via the …

A model treating tensile deformation of semi-crystalline polymers
… polymer materials during the extension process. Uniaxial stretching of a semi-crystalline polymer sample causes the initial spherulitic structure to be deformed and then destroyed, later a fibrillar structure forms. Employing a video-control in the stretching device, we always measured true …

Mechanics of living cells: nonlinear viscoelasticity of single fibroblasts and shape instabilities in axons
… first part of this report describes single-cell uniaxial stretching experiments performed on fibroblasts. When placed between fibronectin coated microplates, fibroblasts adopt a regular, symmetrical shape and generate forces. When a constant cell length is imposed, an increase with time of the …

Anisotropic Morphologies and Properties in Perfluorosulfonate Ionomer-Based Materials
… crystalline domains. Specifically, the effect of uniaxial orientation on the structure and transport properties of Nafion® membranes was examined. Small angle X-ray scattering (SAXS) experiments on dry membranes that were uniaxially elongated showed a strong anisotropic morphology which was shown …
