Abstract: The paper investigates the performance of a novel three-node edge-based smoothed finite element method incorporating an automatic adaptive mesh refinement algorithm to provide the solutions of practical engineering mechanics problems under stress concentration. Due to its simplicity and numerical stability, the three-node triangular element works well with mesh adaptive and strain smoothing procedures. The proposed adaptive mesh implementation adopts the vertex bisection algorithm with recoverybased error estimators that automatically decides the critical remeshing elements based on the discrepancy between numerical solutions and the so-called recovery solution. The specific error indicator with recovery technique in L2-norm is adopted in the present work. Some numerical examples are given to illustrate efficiency and accuracy of the results obtained from the proposed analysis framework. It describes a significant reduction of computing resources as compared to standard model construction procedures
