Question:
We wish to generalize the findings in Exercise 3.8 , and thus consider a stress field of the general form σij = Pfij (xk), where P is a loading parameter and the tensor function fij specifies only the field distribution. Show that the principal stresses will be a linear form in P, that is, σ1,2,3 = Pg1,2,3(xk). Next demonstrate that the principal directions will not depend on P.
Data from exercise 3.8
Exercise 8.2 provides the plane stress (see Exercise 3.5) solution for a cantilever beam of unit thickness, with depth 2c, and carrying an end load of P with stresses given by:
