5 Concluding Remarks
As this chapter was essentially completed and first submitted in June 2015, there are several articles that came to our attention since then and more progress was made on the topic of gradient mechanics by our Lab collaborators and other authors. While it is impossible to expand in detail on all these developments, it is only fair to provide a brief account on various issues that have not been elaborated or touched upon here.
5.1 Generalized Continuum Mechanics Aspects
Even though not explicitly stated by a number of prominent continuum mechanics authors in the recent literature, the revival of interest on second deformation gradient materials (i.e., the early contributions of Mindlin, Toupin, Rivlin, Eringen, etc., in the ...
