BEM-FEM coupling is desirable for three-dimensional probl ems involving specific features such as (i) large or unbounded media with linear constitutive pro perties, (ii) cracks, (iii) critical parts of complex geometry requiring accurate stress analyses. Howe ver, for cases with a BEM discretization involving a large number NBEM of degrees of freedom, setting up the BEM contribution to the coupled problem using conventional techniques is an exp ensiveO(N BEM) task. Moreover, the fully-populated… CONTINUE READING
