A reduced integration solid‐shell finite element based on the EAS and the ANS concept—Large deformation problems

Abstract: SUMMARYIn this paper we address the extension of a recently proposed reduced integration eight-node solid-shell finite element to large deformations. The element requires only one integration point within the shell plane and at least two integration points over the thickness. The possibility to choose arbitrarily many Gauss points over the shell thickness enables a realistic and efficient modeling of the non-linear material behavior. Only one enhanced degree-of-freedom is needed to avoid volumetric and Poisson… Show more

“…From these tests, we found out that the use of the second or the third ANS version (see Figure 3) leads almost to the same results. This observation agrees with the remark of Cardoso et al [32] and Schwarze and Reese [10] concerning the use of a full integration scheme. Therefore, the second ANS version is used for SSH3D solid-shell element.…”

“…The pinched hemisphere with an 18° hole is a popular benchmark and one of the most stringent examples to test the behavior of the finite element formulation in geometrical non-linear domain due to its double curvature [6,8,10,22,47,48]. As shown in Figure 13 the problem consists in a hemispherical shell with an 18° hole at the top subjected to concentrated forces, i.e.…”

“…A solid-shell finite element discretization is adopted, by using the element proposed in [15] and successive modifications (in particular we use the selective mass scaling described in [3] and [4]). In the paper we assume the following numbering for the reference element: since the thickness is small, it is always possible to identify nodes 1-4 for the lower surface, and nodes 5-8 for the upper surface.…”
