“…Later on, the combination of strain/gradient smoothing and FEM is named smoothed FEM (SFEM). 54 SFEMs can be classified into different types based on the distinct constructions of SDs, for example, cell-based SFEM (CS-FEM), [58][59][60][61][62][63][64][65][66][67][68][69][70][71][72] node-based SFEM (NS-FEM), [73][74][75][76][77][78][79][80][81] edge-based SFEM (ES-FEM), [82][83][84][85][86][87][88][89] face-based SFEM, [88][89][90][91] 𝛼FEM, [92][93][94] 𝛽FEM, 95,96 and selective SFEM. [97][98][99][100] Different constructions of SDs lead to different extents of softening.…”

“…Kim et al [31] adopted variable-node elements (VNEs) in two-dimensional contact problems with nonmatching meshes. However, a VNE is not generally applicable to arbitrary nonmatching meshes in three-dimensional problems because of the restricted distribution of additional nodes [32].…”

“…Another class of coupling strategies consists of methods based on non-conventional types of elements [22,23,24]. These methods modify the element formulation in order to convert the nonmatching interface into a matching one.…”

“…The capability of the interface element method was improved in handling curved interface by employing the moving least square approximation [23]. Besides, polyhedron elements [24] are developed to deal with non-matching interfaces based on the cell-based smoothed nite element method [27]. Such a coupling strategy can potentially be employed with other formulations of polytope elements [28,29,30,31,32,33, to name a few].…”
