β¦ Synopsis
We determine transformations of generalised coordinates which can be used as symmetry transformations for simple materials. We also find the general forms of the constitutive equation for isotropic and fluid shells. * Cf Vol.III of [3], Chap XV, Β§2 were we take h = (F, O) and O(X, t) = O0, a constant. ** Composition of maps is read from fight to left. * We shall use square and round brackets interchangeably for more clarity of expression. * This is due to Cauchy. ** Cf [2]. *** Here, A s = Β½(A + AT). * This is because if S does not work, we can change it to SD by the last statement. ** The c's are non-zero from physical considerations.
