Notes:
The reason for looking in some depth at locking of Mindlin shell elements is introduced.A simple example of straight beam locking is examined in detail.The observations about reduced integration that emerge are subsequently unified with some other facts the writer has come across.A simple curved beam element is then formulated and examined under inextensional bending. The performance of this element under reduced integration is predicted for both the ‘undistorted’ and ‘distorted’ configurations (see text) and for a selective-very reduced integration scheme.The previous predictions are then verified through the performance of an 8 node Mindlin shell element in a suitable cylindrical shell test.The paper finally concludes with a set of important observations that so easily could be drawn from such a simple analysis.
