Figure 1.23 Geometry and loading for out-of-the-plane compliance derivation
The out-of-the-plane displacements at point 1 can be again calculated by
means of Castigliano’s second theorem as:
where the strain energy is:
After performing the calculations of Eqs. (1.134), (1.135) and (1.136), the
out-of-the-plane displacements and loads can be connected as:
