N2 - This paper presents a coupling algorithm between a non-local particle method (the volume compensated particle method, VCPM) and the classical finite element method (FEM) to bring together the advantages of both methods for fracture analysis in large structures. In this algorithm, the discrete VCPM particle and the continuum FEM domains are solved within a unified theoretical framework. A new10-partilces element is developed and used to solve the VCPM particle domain, which serves to provide a seamless linkage with the continuum FEM domain. A transitional technology is also developed to smoothly link the 10- particles element with the traditional FEM elements to guaranty the continuity and consistencyat the coupling interface. The accuracy and efficiency of the coupling algorithm are tested by several benchmark problems.
