Abstract
In this paper, a six-node triangular CO curved shell element is developed b
y the assumed natural or covariant strain (ANS) method. All the sampled nat
ural strains are optimal with respect to the derivative of a prescribed cub
ic field in a subparametric element. Numerical examinations reveal that the
element shows no sign of locking, passes all the patch tests and yields sa
tisfactory accuracy. (C) 1999 Elsevier Science S.A. All rights reserved.
