An optimally convergent discontinuous-Galerkin-based extended finite element method for fracture mechanics
The extended finite element method (XFEM) enables the representation of cracks in arbitrary locations of a mesh. We introduce here a variant of the XFEM rendering an optimally convergent scheme. Its distinguishing features are: a) the introduction of singular asymptotic crack tip fields with support on only a small region around the crack tip, the enrichment region, b) only one and two enrichme...
متن کاملNeural Network Learning Through Optimally Conditioned Quadratically Convergent Methods Requiring NO LINE SEARCH
Neural Network Learning algorithms based on Conjugate Gradient Techniques and Quasi Newton Techniques such as Broyden, DFP, BFGS, and SSVM algorithms require exact or inexact line searches in order to satisfy their convergence criteria. Line searches are very costly and slow down the learning process. This paper will present new Neural Network learning algorithms based on Hoshino's weak line se...
متن کاملFracture & Fatigue Analyses: SGBEM-FEM or XFEM? Part 2: 3D Solids
The SGBEM-FEM alternating method is compared with the recently popularized XFEM, for analyzing mixed-mode fracture and fatigue growth of 3D nonplanar cracks in complex solid and structural geometries. A large set of 3D examples with different degrees of complexity is analyzed by the SGBEM-FEM alternating method, and the numerical results are compared with those obtained by XFEM available in the...
متن کاملA Quadratically Convergent Interior-Point Algorithm for the P*(κ)-Matrix Horizontal Linear Complementarity Problem
In this paper, we present a new path-following interior-point algorithm for -horizontal linear complementarity problems (HLCPs). The algorithm uses only full-Newton steps which has the advantage that no line searchs are needed. Moreover, we obtain the currently best known iteration bound for the algorithm with small-update method, namely, , which is as good as the linear analogue.
متن کاملAnalysis of Sheet Fracture Failure Based on XFEM
Extended finite element method (XFEM) is the most effective numerical method to solve discrete mechanical problem. Crack growth problem of two-dimension finite length rectangle panel is researched based on Abaqus XFEM frame. Stress intensity factor is obtained respectively by theoretical calculation and XFEM simulation, which proves reliability of XFEM and the software.
