Cylindrical Shells

A shell is simply a plate with some curvature; it also supports wave motion, but the curvature complicates the motion considerably. As we will see, however, certain types of shell systems can also be represented by (2+1)D MDKCs. We will look first at the so-called cylindrical membrane shell formulation [77], then at a more modern (and elaborate) cylindrical shell formulation due to Naghdi and Cooper [31,128].
