A new model for thin plates with rapidly varying thickness. III. Comparison of different scalings. (English) Zbl 0605.73048
This paper continues a series of papers on bending of plates with varying thickness [see parts II and I, ibid. 43, 1-22 (1985; Zbl 0565.73046) and Int. J. Solids Struct. 20, 333-350 (1984; Zbl 0532.73055)]. There are three different regimes: slow variation, variation on the same scale as the mean thickness and fast variation. After a brief review of the three models the case is investigated when the thickness is a function of a single variable. For a general thickness function the results are less complete. The conclusions have implications for structural optimization.
