Abstract Recently, a series of isoparametric boundary elements have been constructed to simulate the shape of holes,
tubes, disks, rings and spheres based on the Lagrange interpolation formulation and the closure condition
at two ends of an arc. These elements can simulate the models which contain the shapes mentioned above
with less nodes and less elements than the conventional boundary elements. However, the basis of those
elements, i.e., hole elements, have the poor accuracy when the number of nodes is less than 6. To improve
these elements, two kinds of improvements are proposed in this study.… More >
