Edge-based smoothed extended finite element method for dynamic fracture analysis

Wu, L. and Liu, P. and Shi, C. and Zhang, Z. and Bui, Tinh Quoc and Jiao, D. (2016) Edge-based smoothed extended finite element method for dynamic fracture analysis. Applied Mathematical Modelling, 40 (19-20). pp. 8564-8579. ISSN 0307-904X


In this paper, the edge-based smoothed extended finite element method (ES-XFEM) is applied to the dynamic fracture analysis of two-dimensional elastic solids. The dynamic stress intensity factor (DSIF) is deduced from J-integral with the train smoothing method. With the deduced DSIF, the implementation of numerical integration and sub-smoothing regions are numerically verified in dynamic fracture behaviors of linear elastic solids. The analysis shows that ES-XFEM is an efficient numerical approach to simulate the dynamic fracture problems.
