THE ROTATIONALLY PERIODIC SYMMETRY IN BEM

Yang Haitian (Department of Engineering Mechanics,Dalian University of Technology,P.R.China) Wu Gaofeng Wu Jingning (Research Institute of Engineering Mechanics,Dalian University of Technology,P.R.China)  
Rotationally periodic symmetry is exploited in 2-D elastostatic calculation using the BEM.It is proved that the coefficient matrices of the global boundary element equations for the rotationally periodic system are block-circulant so long as a kind of symmetry-adapted reference coordinate system is adopted. Furthermore,an efficient algorithm,which partitions the original problem of solving the boundary element equations into a series of subproblems,is proposed.The method permits arbitrary load distribution for stress analysis problems.
