Abstract
In this paper, one of the variants of the smoothed finite element method, α-FEM is adopted for hyperelastic material with large deformation and contact nonlinearity in two dimensions. The salient feature of the α-FEM is that it is stable and this is accomplished by using the scale factor α [0, 1] to combine the compatible finite element method and the node-based smoothed finite element method. The framework is implemented in the commercial software, Abaqus using the user element feature, UEL. The efficacy and robustness of the proposed work is demonstrated by several benchmark problems in both linear and nonlinear elasticity with and without contacts.
