Shell Structures On the basis of the strength-to-weight ratios, one of the most efficient of nature’s structures is the shell. Consequently, there are numerous applications of shell structures in various areas of science and technology. Thin shells have been increasingly adopted as an efficient way to cover up large spaces due to its potential.


When analyzing more complex problems, an effective approach for inhibiting errors from occurrence is to use analytical techniques so as to test the Finite Element program over simpler examples. Despite numerous techniques being developed to overcome the convergence problems, however, the sequentially linear analytical (SLA) technique has an edge over the others when modeling cracks or damage of full-scale structures since the SLA technique successfully matches the potentials of total strain fixed crack models. Shell Elements: Implementation in Sequentially Linear Analysis The potential of sequentially linear analysis is stretched to 3-D structures by using the shell elements. Although the analysis with complete three dimensional solid elements can be done, however the shell elements offer an efficient way to model numerous conventional structures. The generalized method for the solution is similar to that in the 2-D structures. Conventionally, the shell elements are used in FE analysis when one direction of the structures is thin, for example: the case in floors, walls, and roofs. ...
