摘要

In many industrial applications, the structures are composed of three-dimensional solid continuum and thin shell-like portions. When modelled with finite elements, these structures present geometrical and physical difficulties at the connections of the shell elements to the solid ones, as the nodal degrees of freedom for the two types of elements are incompatible with each other. The development of efficient and reliable transition finite elements is thus of outstanding practical importance. In this paper, a set of C{sup}0 compatible solid to shell transition finite elements, which are based on the isoparametric solid element and the superparametric thick shell element, is presented. The proposed elements, which can be easily implemented in a standard finite element code, show an excellent convergence pattern in structural dynamics analysis. Numerical examples are also presented and compared with experimental cases in order to enhance the accuracy and application of such elements.
