Kirchhoff shell
Webdiscrete-Kirchhoff approach for the analysis of thin shells2,5-9; (2) the use of degenerated isoparametric elements in which fully three-dimensional stress and strain conditions are degenerated to shell behaviour2,3,5,7,17,19,24,29. The latter approach has the advantage of being inde pendent of any particular shell theory, and this approach The Kirchhoff–Love theory of plates is a two-dimensional mathematical model that is used to determine the stresses and deformations in thin plates subjected to forces and moments. This theory is an extension of Euler-Bernoulli beam theory and was developed in 1888 by Love using assumptions … Meer weergeven Let the position vector of a point in the undeformed plate be $${\displaystyle \mathbf {x} }$$. Then The vectors $${\displaystyle {\boldsymbol {e}}_{i}}$$ Meer weergeven The original theory developed by Love was valid for infinitesimal strains and rotations. The theory was extended by von Kármán to situations where moderate rotations could be expected.

They include membrane, bending and shear deformation and the normal stress, through the thickness, is always zero. Figure 1. Shell Element. In Radioss, the standard shell elements are Mindlin plate elements with transverse shear …
WebBoth theories include in-plane shear strains and both are extensions of Kirchhoff–Love plate theory incorporating first-order shear effects. Uflyand-Mindlin's theory assumes that there is a linear variation of displacement across the plate thickness but that the plate thickness does not change during deformation. Webmations is to use the discrete Kirchhoff theory. This approach can directly be employed to establish simple shell elements and our DKT (discrete Kirchhoff trian- gular) element is one of that kind[5-7]. l~oth elements can be employed for large displace- ment and elastic-plastic analysis, but there are distinct
