Abstract EN

An improved 8-node shell finite element applicable for the geometrically linear and nonlinear analyses of plates and shells is presented.

Based on previous first-order shear deformation theory, the finite element model is further improved by the combined use of assumed natural strains and different sets of collocation points for the interpolation of the different strain components.

The influence of the shell element with various conditions such as locations, number of enhanced membranes, and shear interpolation is also identified.

By using assumed natural strain method with proper interpolation functions, the present shell element generates neither membrane nor shear locking behavior even when full integration is used in the formulation.

Furthermore, to characterize the efficiency of these modifications of the 8-node shell finite elements, numerical studies are carried out for the geometrically linear and non-linear analysis of plates and shells.

In comparison to some other shell elements, numerical examples for the methodology indicate that the modified element described locking-free behavior and better performance.

More specifically, the numerical examples of annular plate presented herein show good validity, efficiency, and accuracy to the developed nonlinear shell element.
