2.5 My Shell Loads

\includegraphics[width=14pt]{./Images/ShellLoad.png}My Shell Loads holds sets of loads that you can apply to laminates to perform analysis using Classical Lamination Theory (CLT). You have to create Shell Loads before you can predict failure in chapter Strength. Strictly speaking, shell loads are stress resultants: inplane forces per unit length, moments per unit length, and shear forces per unit length. These are not the actual loads applied to a plate or shell but the internal loads generated while the laminate resists the actual loads. Methods to calculate shell loads in terms of actual loads and boundary conditions for actual structures are discussed in the textbook.

The shell loads can be visualized as follows:
