## Abstract In this paper, the extended finite element method (XβFEM) is investigated for the solution of hydraulic fracture problems. The presence of an internal pressure inside the crack is taken into account. Special tip functions encapsulating tip asymptotics typically encountered in hydraulic
## Abstract The βconventionalβ finite elementβboundary integral (FEβBI) method suffers from two major drawbacks, one is the huge computer resources required by the dense BI submatrix; the other is the slow convergence rate of the resulting linear system of equations. In this article, both the drawb
An rh-method, which combines r-and h-methods, is proposed for cost-eective adaptive FE analysis in twodimensional linear elastic problems. Through various numerical test examples, the rh-method is compared with the h-method. From these examples it is concluded that the rh-method has the advantages o
