Two minor epiphanies; 1) the expression Partial wrt "s" of d(k)=u x d(k) is a restatement that "d" follows "u" and 2) the compatibility equation is the long sought after nonlinear coupling of torsional and transverse moments. I therefore know that in uniplanar responses w= Partial wrt "t" of the Integral (u) wrt "s".
