Abstract
Recently, Liu et al. proposed the smoothed finite element method by using the nonβmapped shape functions and then introducing the strain smoothing operator when evaluating the element stiffness in the framework of the finite element method. However, the theories and examples by Liu et al. are not sufficient for general quadrilateral elements. This paper shows that the nonβmapped shape functions used in the smoothed finite element have disadvantages in existence, linearity, nonβnegativity and patch test.

## Abstract Verification of the computation of local quantities of interest, e.g. the displacements at a point, the stresses in a local area and the stress intensity factors at crack tips, plays an important role in improving the structural design for safety. In this paper, the smoothed finite elem
