Abstract
A new local coordinate system is introduced for the assumed strain formulation so that the resulting shell element can pass both the patch test and the locking test. The coordinate system is tested by implementing it in two nine-node assumed strain shell elements. The elements adopting the new local coordinate system not only pass various patch tests successfully but also perform well in locking tests.
