Effect of Prestrain on the Actuation Characteristics of Dielectric Elastomers. [PDF]
Polymers (Basel), 2020 Dielectric elastomers (DEs) represent a class of electroactive polymers that deform due to electrostatic attraction between oppositely charged electrodes under a varying electric field. Over the last couple of decades, DEs have garnered considerable attention due to their much-coveted actuation properties.

Engineering StructuresShape memory coupling technologies offer an alternative to welded, machined and bonded joints. They provide advantages such as self-locking assembly, reduced stress concentration, rapid installation, suitability for confined spaces, and in some cases cost efficiency.

Material Effects on Tangent Modulus of Steel Square Hollow Section [PDF]
Journal of Rehabilitation in Civil Engineering, 2023 The kind of mild steel, the Bauschinger effect because of strain reversal and strain ageing are indicated to affect significantly the tangent modulus of elasticity.

Journal of Materials Research and Technology, 2022 We investigated the effect of different Cu additions (0.1 wt.% and 0.3 wt.%) on the precipitation activation energy and mechanical properties of Al–Mg–Si alloys under different prestraining levels (0%, 3%, and 5%). Tensile tests were performed before and

Influence of Prestraining on Tangent Modulus of Tubular Struts [PDF]
Fanāvarī-i āmūzish, 2006 Strain reversal in the inelastic range may cause a dramatic drop in the tangent modulus for mild steel struts. Other material properties also affect the tangent modulus.

A Homogenized Bending Theory for Prestrained Plates
Journal of Nonlinear Science, 2022 AbstractThe presence of prestrain can have a tremendous effect on the mechanical behavior of slender structures. Prestrained elastic plates show spontaneous bending in equilibrium—a property that makes such objects relevant for the fabrication of active and functional materials. In this paper we study microheterogeneous, prestrained plates that feature

Plates with Incompatible Prestrain [PDF]
Archive for Rational Mechanics and Analysis, 2016 We study the effective elastic behavior of incompatibly prestrained plates, where the prestrain is independent of thickness as well as uniform through the thickness. We model such plates as three-dimensional elastic bodies with a prescribed pointwise stress-free state characterized by a Riemannian metric $G$ with the above properties, and seek the ...

Plates with incompatible prestrain of high order [PDF]
Annales de l'Institut Henri Poincaré C, Analyse non linéaire, 2017 We study the elastic behaviour of incompatibly prestrained thin plates of thickness h whose internal energy E^{h} is governed by an imposed three-dimensional smooth Riemann metric G

Heterogeneous growth-induced prestrain in the heart [PDF]
Journal of Biomechanics, 2015 Even when entirely unloaded, biological structures are not stress-free, as shown by Y.C. Fung׳s seminal opening angle experiment on arteries and the left ventricle. As a result of this prestrain, subject-specific geometries extracted from medical imaging do not represent an unloaded reference configuration necessary for mechanical analysis, even if the
