Automatic Adaptive Recovery Stress ES-FEM for Lower-Bound Limit Load Analysis of Structures

International Journal of Computational Methods, 2021
The paper proposes a novel automatic adaptive recovery stress edge-smoothed finite element method (ES-FEM) that determines the maximum load capacity of inelastic structures at plastic collapse. This approach performs solely a series of elastic ES-FEM analyses with systematic modulus variations (considering the influences of stress singularity) to ...

ES-FEM with ABC for Accurate Parameter Extraction of High Speed Interconnects

2020 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2020
An accurate edge-based smoothed finite element method (ES-FEM) with the absorbing boundary condition (ABC) to model high-speed interconnects is introduced in this paper. In the ES-FEM, the edge-based smoothing domain is first constructed based on the background triangle meshes. Then, by incorporating with the smoothing gradient techniques, the gradient

Fatigue analysis using the singular ES-FEM

International Journal of Fatigue, 2012
Abstract A novel procedure of singular edge-based smoothed finite element method (singular ES-FEM) has been customized for the fatigue crack growth analysis. For this method, a layer of crack-tip elements with special shape functions was adopted to capture the theoretical singularity of the stress field. In addition, a ‘strain smoothing technique’ on

A novel singular ES-FEM for crack growth simulation

Engineering Fracture Mechanics, 2012
Abstract A novel singular seven-node crack-tip triangular element with edge-based strain smoothing is formulated for modeling crack growth in solids. The present singular ES-FEM method uses a basic mesh of linear triangular elements and a special layer of seven-noded crack-tip elements connected to the crack-tip. The seven-noded crack-tip element has

A quasi‐static crack growth simulation based on the singular ES‐FEM

International Journal for Numerical Methods in Engineering, 2011
AbstractIn the edge‐based smoothed finite element method (ES‐FEM), one needs only the assumed displacement values (not the derivatives) on the boundary of the edge‐based smoothing domains to compute the stiffness matrix of the system. Adopting this important feature, a five‐node crack‐tip element is employed in this paper to produce a proper stress ...
