- Abstract
In this work it is presented a coupling between the Boundary Element Method (BEM) and the Finite Element Method (FEM) for two-dimensional elastostatic analysis of frame-solid interaction. The BEM is used to model the matrix while the reinforcement is modeled by the FEM. Regarding the coupling formulation a third degree polynomial is adopted to describe the displacement and rotations of the reinforcement, while a linear polynomial is used to describe the contact force among the domain (matrix) and the reinforcement. Perfect bounding contact forces are improved by means of redundant equations and Least squares method. Slip-bounding with two and three paths written as function of relative displacement are used to calculate the transmitted contact forces. Examples are used to demonstrate that the proposed slip-bounding procedure regularizes the contact force behavior.
