Components and structures are usually constructed according to strength principles. Fatigue crack growth in components and fracture of structures consistently occur due to, e.g. high local stresses, material and manufacturing defects. The following article deals with different examples of crack growth in real structures. These examples shall exemplify learning from damages and consequently preventing failure of components and structures in the future. Furthermore a simulation method is presented to simulate fatigue crack growth in any three-dimensional structures.
