Abstract: | Summary A survey of effective finite element formulations for the analysis of shell structures is presented. First, the basic requirements
for shell elements are discussed, in which it is emphasized that generality and reliability are most important items. A general
displacement-based formulation is then briefly reviewed. This formulation is not effective, but it is used as a starting point
for developing a general and effective approach using the mixed interpolation of the tensorial components. The formulation
of various MITC elements (that is, elements based on Mixed Interpolation of Tensorial Components) are presented. Theoretical
results (applicable to plate analysis) and various numerical results of analyses of plates and shells are summarized. These
illustrate some current capabilities and the potential for further finite element developments. |
