Isogeometric analysis enhanced by the scaled boundary finite element method
No tensor-product patches as only the boundary information is required. Feasible to have n n -sided polygonal domain of mixed type/order of element on edges. Model stress/strain singularities without enrichment. When employed to study dynamic response at high frequencies, the proposed method does not require internal mesh.
