review text: A method for constructing adaptive boundary elements for the elastic stress/deformation analysis of multiple subregions, such as composites, is presented. Discretized integral equations for each subregion in terms of the boundary unknowns and solution errors are combined to obtain linear simultaneous equations for an entire region. A sample point error analysis and an extended error indicator are employed for the error estimation and relevant boundary element refinement using the \(h\)-scheme. The error level at the inner boundary is adjusted by introducing a parameter that indicates the influence of element error at the outer boundary on the solution inconsistency at the inner boundary.
