Use of Fracture Mechanics and Shape Optimization for Component Designs

About half of mechanical failures are due to repeated loading. Most of the failures are fatigue related, and the fatigue problem has been of major concern in the design of structures. The failure is a function of, among other factors, the external loads, material behavior, geometry of the structure,...

Zusammenfassung:	About half of mechanical failures are due to repeated loading. Most of the failures are fatigue related, and the fatigue problem has been of major concern in the design of structures. The failure is a function of, among other factors, the external loads, material behavior, geometry of the structure, and crack characteristics.
