WebApr 1, 1997 · A non-conventional derivation of the stress resultant shell theory is presented, which makes use of the virtual work principle and local Cartesian frames. The presented derivation introduces no simplifying hypotheses regarding the shell balance equations, hence the resulting shell theory is referred to as being geometrically exact. Webapproach is attributed as geometrically exact shell theory. An alternative point of departure has been provided by Reissner [26]. It has been recast by Ibrahimbegovic [17]. Via the application of a non-symmetric Biot-type strain measures the drilling dof enters the virtual work principle. Here these type of shell theories are called micropolar.
