Abstract

Fourth-order tensors play an important role in continuum mechanics where they appear as elasticity and compliance tensors. In this section we define fourth-order tensors and learn some basic operations with them. To this end, we consider a set \(\varvec{\mathcal {L}}\text {in}^n\) of all linear mappings of one second-order tensor into another one within \(\mathbf {L}\text {in}^n\). Such mappings are denoted by a colon as
$$ \mathbf {Y}=\varvec{\mathcal {A}} : \mathbf {X}, \quad \varvec{\mathcal {A}}\in \varvec{\mathcal {L}}\text {in}^n, \; \mathbf {Y}\in \mathbf {L}\text {in}^n, \; \forall \mathbf {X}\in \mathbf {L}\text {in}^n.$$
