Concurrent fatigue crack growth simulation using extended finite element method

Zizi LU, Yongming LIU,

Frontiers of Structural and Civil Engineering 2010, Volume 4, Issue 3,   Pages 339-347 doi: 10.1007/s11709-010-0078-2

Abstract: In this paper, a concurrent simulation framework for fatigue crack growth analysis is proposed usinga novel small time scale model for fatigue mechanism analysis and the extended finite element method(X-FEM) for fatigue crack growth simulation.The X-FEM greatly facilitates crack growth simulation without remeshing requirements ahead of the cracktip as in the classical finite element method.

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.
