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 temperature dependent large-deformation response of amorphous polymeric materials. Such a theory, when further specialized (Part II) should be useful for modeling and simulation of the thermo-mechanical response of components and structures made from such materials, as well as for modeling a variety of polymer processing operations.

A large deformation viscoelastic model for double-network hydrogels (2017, methodology): “3 A theory based on a decomposition of the form (3.1) has also been successfully used for modeling the behavior of glassy polymers, both below and above their glass transition temperatures (cf., e.g., Boyce et al., 2000; Anand et al., 2009; Ames et al., 2009; Srivastava et al., 2010a, 2010b).”
A thermo-mechanically-coupled large-deformation theory for amorphous polymers in a temperature range which spans their glass transition (2010, methodology): “In a recent pair of papers we have developed a thermo-mechanically-coupled large-deformation theory (Anand et al., 2009; Ames et al., 2009); however, this theory, like the others listed above, is also limited to a temperature range below the glass transition temperatures of such materials.”
Mapping thixo-elasto-visco-plastic behavior (2017, background): “The tensorial quantity A can be related to an elastic free energy function (see Dimitriou et al. 2013, Appendix B, and Ames et al. 2009 for additional details) and therefore more complex relationships than a direct linear relationship between the components of the back stress tensor andA can easily…”
