摘要：
In this study,the stress based finite element method is coupled with the boundaryelement method in two different ways.In the first one,the ordinary distribution matrix is used forcoupling.In the second one,the stress traction equilibrium is used at the interface line of both regionsas a new coupling process.This new coupling procedure is presented without a distribution matrix.Several case studies are solved for the validation of the developed coupling procedure.The results ofcase studies are compared with the distribution matrix coupling,displacement based finite elementmethod,assumed stress finite element method,boundary element method,ANSYS and analyticalresults whenever possible.It is shown that the coupling of the stress traction equilibrium with assumedstress finite elements gives as accurate results as those by the distribution matrix coupling.
