A coupled theory of fluid permeation and large deformations for elastomeric materials
Abstract An elastomeric gel is a cross-linked polymer network swollen with a solvent (fluid). A continuum-mechanical theory to describe the various coupled aspects of fluid permeation and largeExpand

A thermo-mechanically-coupled large-deformation theory for amorphous polymers in a temperature range which spans their glass transition
Abstract Amorphous thermoplastic polymers are important engineering materials; however, their non-linear, strongly temperature- and rate-dependent elastic-viscoplastic behavior is still not very wellExpand

A thermo-mechanically coupled theory for fluid permeation in elastomeric materials: Application to thermally responsive gels
Abstract An elastomeric gel is a cross-linked polymer network swollen with a solvent, and certain gels can undergo large reversible volume changes as they are cycled about a critical temperature. WeExpand

Printing ferromagnetic domains for untethered fast-transforming soft materials
Soft materials capable of transforming between three-dimensional (3D) shapes in response to stimuli such as light, heat, solvent, electric and magnetic fields have applications in diverse areas suchExpand

A finite element implementation of a coupled diffusion-deformation theory for elastomeric gels
TLDR
The theory of Chester and Anand (2011) for fluid diffusion and large deformations of elastomeric gels is implemented as a user-defined element (UEL) subroutine in the commercial finite element software package ABAQUS. Expand

A thermo-mechanically coupled theory for large deformations of amorphous polymers. Part II: Applications
In this Part I, of a two-part paper, we present a detailed continuum-mechanical development of a thermo-mechanically coupled elasto-viscoplasticity theory to model the strain rate and temperatureExpand

A large-deformation gradient theory for elastic–plastic materials: Strain softening and regularization of shear bands
We present a large deformation gradient theory for rate-independent, isotropic elastic–plastic materials in which in addition to the standard equivalent tensile plastic strain ϵ¯p, a variable ep isExpand
