Abstract
In a method of making a recess termination in a component, the recess (2) extending with its tip (4) from the surface (3) of a wall (1) of the component into the interior of the wall (1), the tip (4) of the recess (2) is deflected in its direction by at least about 180.degree. relative to the main extension direction of the recess (2), the deflection being effected in a curvature (6) which is generously dimensioned from the point of view of notch and fracture mechanics, the maximum radius (4) of curvature being placed at the point of maximum stress in the wall (1), the tip (4) of the recess (2) ending in an at least largely relieved region, and the wall piece in the interior of the arc (6) of curvature remaining connected to the rest of the wall (1) via an adequately dimensioned material bridge (5).
