Abstract Scope |
During the last decades Mg and alloys gained interest as degradable implant materials: its mechanical 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 microstructure development. However, this is not 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 buckling 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 engineering. Besides the proper mechanical properties, degradation behaviour, biocompatibility etc. the geometry can be of crucial importance and should be considered prior to design of alloys and their processing. |
