英文摘要Smoothed finite element method with the node-based strain smoothing domains (NS-FEM) is remarkable for the upper-bound feature and insensitivity to the volumetric locking. As a mesh-based methodology, its application is limited by the burdensome meshing for which elements align with the physical domain. We extend the strain smoothing in NS-FEM to the numerical manifold method (NMM) with unfitted meshes, and propose a novel methodology named physical patch-based smoothed NMM. Benchmark problems demonstrate the optimal convergence, stability in term of the condition number, upper-bound property, suppression of the volumetric locking, as well as the stress stability.
