Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 2, Pages 456-477 doi: 10.1007/s11709-019-0519-5

Abstract:

The smoothed finite element method (S-FEM) was originated by G R Liu by combining some meshfree techniqueswith the well-established standard finite element method (FEM).A number of important properties and unique features of S-FEM models are discussed in detail, includingThe S-FEM is thus ideal for automation in computations and adaptive analyses, and hence has profoundas wish, meaning that S-FEM offers a framework for design numerical models with desired properties.

3D finite element method (FEM) simulation of groundwater flow during backward erosion piping

Kristine VANDENBOER,Vera van BEEK,Adam BEZUIJEN

Frontiers of Structural and Civil Engineering 2014, Volume 8, Issue 2, Pages 160-166 doi: 10.1007/s11709-014-0257-7

Abstract: Backward erosion piping is an important failure mechanism for cohesive water retaining structures which are founded on a sandy aquifer. At present, the prediction models for safety assessment are often based on 2D assumptions. In this work, a 3D numerical approach of the groundwater flow leading to the erosion mechanism of backward erosion piping is presented and discussed. Comparison of the 2D and 3D numerical results explicitly demonstrates the inherent 3D nature of the piping phenomenon. In addition, the influence of the seepage length is investigated and discussed for both piping initiation and piping progression. The results clearly indicate the superiority of the presented 3D numerical model compared to the established 2D approach. Moreover, the 3D numerical results enable a better understanding of the complex physical mechanism involved in backward erosion piping and thus can lead to a significant improvement in the safety assessment of water retaining structures.

Maximum entropy based finite element analysis of porous media

Emad NOROUZI, Hesam MOSLEMZADEH, Soheil MOHAMMADI

Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 2, Pages 364-379 doi: 10.1007/s11709-018-0470-x

Abstract: The maximum entropy theory has been used in a wide variety of physical, mathematical and engineering applications in the past few years. However, its application in numerical methods, especially in developing new shape functions, has attracted much interest in recent years. These shape functions possess the potential for performing better than the conventional basis functions in problems with randomly generated coarse meshes. In this paper, the maximum entropy theory is adopted to spatially discretize the deformation variable of the governing coupled equations of porous media. This is in line with the well-known fact that higher-order shape functions can provide more stable solutions in porous problems. Some of the benchmark problems in deformable porous media are solved with the developed approach and the results are compared with available references.
