A Comparative Study of the Entanglement Models Toward Simulating Hyperelastic Behaviors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Accurately predicting the hyperelastic response of soft materials under complex loading conditions has been a long-standing challenge. Previous developments have shown that incorporating the entanglement effect can ...
Modeling the Thermoviscoelastic Properties and Recovery Behavior of Shape Memory Polymer Composites
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work investigated the effects of stiff inclusions on the thermoviscoelastic properties and recovery behavior of shape memory polymer composites. Recent manufacturing advances have increased the applicability and ...
An Experimental Study on Strain Hardening of Amorphous Thermosets: Effect of Temperature, Strain Rate, and Network Density
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present an experimental study on strain hardening of amorphous thermosets. A series of amorphous polymers is synthesized with similar glass transition regions and different network densities. Uniaxial ...
The Temperature Dependent Viscoelastic Behavior of Dielectric Elastomers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we investigated the temperaturedependent viscoelastic behavior of dielectric elastomers (DEs) and the effects of viscoelasticity on the electroactuation behavior. We performed dynamic thermomechanical analysis ...
Identification of Creep Camber State of 32-m Box Girders on High-Speed Railway and Prediction of Geometry of Track over Girder
Publisher: ASCE
Abstract: The creep camber of box girders significantly lowers track regularity, making it very important to perform track geometry precise adjustment or ballast tamping operations by maintenance machinery on box girder sections at ...
