N2 - During the last decades, MgMg and alloys gained interest as degradable implant materials: its mechanical propertiesMechanical properties are close to bone and a second surgery for removing them can be avoided. Properties are gained from chemical composition and processing as they are responsible for microstructureMicrostructure development. However, this is not good enough in many cases. When the implant e.g. has a high aspect ratio (length/cross section), additional requirements need to be considered: Euler cases. L. Euler described this firstly in 1744 that bucklingBuckling and catastrophic failure can occur at a certain fracture force for a given length and cross section area. The latter can be easily calculated by area moments of inertia which are well known in civil and mechanical engineering. Besides the proper mechanical propertiesMechanical properties, degradationDegradation behaviour, biocompatibility, etc., the geometry can be of crucial importance and should be considered prior to design of alloys and their processing.
