摘要
A least-squares finite element method (LSFEM) for bending problems of thin plates is developed. This LSFEM is based on the first-order deflection-slope-moment-shear force formulation. Four compatibility conditions are added into the first-order system; thus, the method can accommodate all kinds of equal-order interpolations. Numerical experiments on various examples show that the method achieves an optimal rate of convergence for all eight variables. Copyright (C) 2002 John Wiley Sons, Ltd.
