On evaluation of influence coefficients for edge and intermediate boundary elements in 3D problems involving strong field concentrations
The paper presents a tool for accurate evaluation of high field concentrations near singular lines, such as contours of cracks, notches and grains intersections, in 3D problems solved the BEM. Two types of boundary elements, accounting for singularities, are considered: (i) edge elements, which adjo...
