Fatigue analysis can be used during the design phase to predict future component failures. This is done through a process called finite element analysis (FEA). With this information, a method of performing preventive maintenance (reducing warranty costs and maximizing product life) can be determined.
Fracture mechanics and fatigue analysis are essential to understanding the structural performance of real world materials. Fracture mechanics is the study of the complex stress field around the tip of a crack and can be used to determine if an existing crack will propagate or arrest. Fatigue analysis is the study of the fracture behavior under repeated cyclic loading.
All materials and equipment over time will at some point be subject to fatigue and break down. Fatigue testing involves the process of taking a sample and applying force in a repeated fashion to see when it will break or how it performs. Materials and equipment are subject to many different applications and environments and require different types of fatigue analyses.
Performing F. analysis can predict component failures during the design phase. The design can then be adjusted or a preventive maintenance schedule can be implemented in order to reduce warranty costs and maximize product life.
