  "textContent": "The invention relates to a thermally and/or mechanically stressed component wall (5) of a fluid-conducting and/or gas-conducting component, in particular a cylinder head (1) of an internal combustion engine, with at least one area at risk of cracking due to the stress, in which a crack develops operationally from the outer wall surface into the component wall (5), and with at least one crack stopper (6) which is arranged in the component wall (5) in the crack path and prevents further crack propagation, in particular through the component wall (5) into critical component areas (8). According to the invention, a crack starter (4) is provided in the crack-prone area (5; 10) on the outer wall surface, which forms a defined localized crack initiation point, so that locally uncontrolled crack formation and crack propagation is prevented.",
