Application of the Extended EFG Method and Cohesive Crack Model to the Crack Growth Analysis of Concrete Structures

摘要

In the paper coupling of the Element Free Galerkin Method with Fictitious CrackrnModel in analysis of cracks growth in concrete plain structure is presented. The displacementrnu0002elds is approximated by the extended approximation of moving weightedrnleast square approximation. The special discontinuous enriching functions is constructedrnto cope with the propagation of the crack. The nonlinear set of incrementalrnequations is formulated and solved by Newton?Raphson procedure.
