Vibration testing and dynamic studies of relays [PDF]
, 1968 Study has been undertaken to determine the separation criteria for a preloaded, idealized set of contacts when they are subjected to a steady-state sinusoidal excitation and when the elasticity of one contact is nonlinear.

Nonlinear Elasticity of Single Collapsed Polyelectrolytes
, 2004 Nonlinear elastic responses of short and stiff polyelectrolytes are investigated by dynamic simulations on a single molecule level. When a polyelectrolyte condensate undergoes a mechanical unfolding, two types of force-extension curves, i.e., a force ...

Selection Strategies for Flexible Pressure Sensor Electrode Materials Toward Ultrafast Response
Advanced Functional Materials, EarlyView.This study reveals, for the first time, how the electrode–organic interface governs the temporal performance of flexible pressure sensors. By pairing high‐conductivity CVD PEDOT with commonly used metal electrodes, the authors demonstrate that interfacial energy alignment dictates microsecond‐scale response, providing a straightforward design strategy ...

Nonlinear Mechanical Response of DNA due to Anisotropic Bending Elasticity
, 2002 The response of a short DNA segment to bending is studied, taking into account the anisotropy in the bending rigidities caused by the double-helical structure. It is shown that the anisotropy introduces an effective nonlinear twist-bend coupling that can

Nonlinear elasticity in rocks: A comprehensive three-dimensional description
, 2017 We study theoretically and experimentally the mechanisms of nonlinear and nonequilibrium dynamics in geomaterials through dynamic acoustoelasticity testing. In the proposed theoretical formulation, the classical theory of nonlinear elasticity is extended

Nonlinear elasticity of semiflexible filament networks. [PDF]
Soft Matter, 2016 We develop a continuum theory for equilibrium elasticity of a network of crosslinked semiflexible filaments, spanning the full range between flexible entropy-driven chains to stiff athermal rods.

On nonlinear thermo-electro-elasticity [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2016 Electro-active polymers (EAPs) for large actuations are nowadays well-known and promising candidates for producing sensors, actuators and generators. In general, polymeric materials are sensitive to differential temperature histories. During experimental characterizations of EAPs under electro-mechanically coupled loads, it is difficult to maintain ...

Robust and Reversible Thermofluorescence in Solvent‐Free Thermoplastic Polyurethane Composites
Advanced Functional Materials, EarlyView.Thermofluorescent polymer composites with high‐contrast optical outputs are prepared by solvent‐free blending of indenoquinacridone dye into a thermoplastic polyurethane matrix. The temperature‐dependent fluorescence originates from aggregation–dissociation of the dye molecules, regulated by competing hydrogen bonds from the polymer matrix.
