Abstract

We construct conforming finite elements for the spaces H(symCurl)H(\text{sym}\,\text{Curl}) and H(devsymCurl)H(\text{dev}\,\text{sym}\,\text{Curl}). Those are spaces of matrix-valued functions with symmetric or deviatoric-symmetric Curl\text{Curl} in a Lebesgue space, and they appear in various models of nonstandard solid mechanics. The finite elements are not H(Curl)H(\text{Curl})-conforming. We show the construction, prove conformity and unisolvence, and point out optimal approximation error bounds.
