In this paper, one of the variants smoothed finite element method, [Formula: see text]-FEM is adopted for hyperelastic material with large deformation and contact nonlinearity in two dimensions. The salient feature that it stable accomplished by using scale factor text] to combine compatible method node-based method. framework implemented commercial software, Abaqus user feature, UEL. efficacy robustness proposed work demonstrated several benchmark problems both linear nonlinear elasticity...
The title problems, considered difficult hitherto, are solved here using a rigorous superposition method comprising of elegant and exact infinite series counterparts the conventional Levy-type solutions. summed without truncation to avoid any loss accuracy. After due validation studies, numerical results tabulated for some typical plate problems use as baseline solutions in future.
In this paper, three different smoothed finite element method (SFEM), viz., node-based (NS-FEM), face-based (FS-FEM) and [Formula: see text]-finite ([Formula: text]-FEM) are adopted for 3D solids undergoing large deformation. The common feature of all these techniques is the introduction strain which written as a weighted average compatible field over smoothing domains. choice domain what differentiates them. spatial discretization can be based on simplest automatically genera-table...
In this work, we propose to replace the conventional flat stainless steel gasket in flanged bolted joints used seawater piping with an O-ring polymer provide a leak-proof joint under bolt preload. Modeled as hyperelastic material, undergoes large deformation when sandwiched between pipe flanges. To alleviate commonly encountered problems due element distortion, use variant of smoothed finite element, α− SFEM within Abaqus standard simulate joint. A systematic study is performed arrive at...
