In many cases, components and structures are designed for a certain service life. If this is exceeded, the initial design assumptions no longer apply. Further use is formally subject to an increased safety risk. What can be done?
With fracture-mechanical fatigue calculations, we can determine statements about possible service life extensions and redefine inspection intervals. The method is technically recognised, but requires special prior knowledge for the determination of boundary conditions and the selection of adapted material characteristics.
If cracks occur, the remaining service life can also be determined using this method. This gives planning security.
Sustainable handling of steel structures. For us, this means calculating the service life while safeguarding against risks as far as possible. With the help of fracture mechanics calculations, we can determine statements about the further service life of an affected component and find short-term solutions for its safety.
