چکیده
The authors have been developing a crack propagation analysis system that can deal with arbitrary shaped cracks in threedimensional solids. The system is consisting of mesh generation software, a large-scale finite element analysis program and a fracture mechanics module. To evaluate the stress intensity factors, a Virtual Crack Closure-Integral Method (VCCM) for the second-order tetrahedral finite element is adopted and is included in the fracture mechanics module. The rate and direction of crack propagation are predicted by using appropriate formulae based on the stress intensity factors. Combined with ADVENTURE system, a large-scale fully automatic fracture analysis can be performed on ES2.

Fracture mechanics-based life prediction of a riveted lap joint
In this paper, three-dimensional modeling of the fatigue crack growth profiles was performed in a simple riveted lap joint. Simulation results showed that mode I was dominated on the one side of the plates and the crack straightly grew on this side, while the other side of the plates was in a mixed-mode condition and the crack propagation path was not straight on this side. Afterward, the fract...

In fracture mechanics and failure analysis, cracked media energy and consequently stress intensity factors (SIFs) play a crucial and significant role. Based on linear elastic fracture mechanics (LEFM), the SIFs and energy of cracked media may be estimated. This study presents the novel modification of decoupled scaled boundary finite element method (DSBFEM) to model cracked media. In this metho...
متن کامل4D geomechanical simulations for field development planning
3D and 4D geomechanical can be time-consuming to build and calibrate. However, once such a model is built, it is relative straightforward to use this model for various field development and management applications. In so doing, the return on the initial investment of time and effort in the creation of a 4D geomechanical model can be substantial. I present a case study where a 4D geomechanical m...
