There are several factors that influence fatigue strength, including: Smoothing and/or polishing are also used to minimize stress risers.

This includes case hardening using a carburizing or nitriding process or shot peening the surface in order to induce residual compressive stresses. These processes focus of enhancing the surface properties of a component. Several processes may be used to extend the fatigue life of a metal component. What is the strength of the component with a fatigue crack? 1.

These engineers are concerned with answering the following questions: Some engineers dedicate their careers to specializing in fatigue mechanics in order to better predict the life expectancy of a component. The fatigue-induced fracture surfaces of a broken component are typically smooth and show no evidence of plastic deformation. Fatigue failures typically occur suddenly. catastrophic fracture) can be ductile or brittle, depending on the material, thickness, temperature and the applied stress. Stage 3: Failure - The final failure event (i.e. Stage 2: Crack propagation - Once a crack is initiated, continued cyclical stresses repeat the process, slowly growing the micro-crack, which becomes a threat to structural integrity. Once the metal reaches its plastic deformation limit, the discontinuity become a small crack. As the metal becomes work hardened, it loses its ability to plastically deform in the localized area where cyclic stresses are evident. This phenomenon is called work hardening. The generation and movement of discontinuities actually strengthens the metal through plastic deformation. The initial development of a fatigue crack occurs at localized discontinuities in the metal’s crystal structure.

Stage 1: Crack initiation - Fatigue cracks almost always initiate at a free surface and near a stress riser (e.g. One of the intriguing factors about fatigue development is that fatigue cracks can be initiated and propagated at stresses well below the yield strength of the material of construction (these stresses are usually thought to be related to elastic deformation, not plastic deformation. While applied stresses may be tensile, compressive or torsional, crack initiation and propagation are due to the tensile component. Fatigue is a failure mechanism that involves the cracking of materials and structural components due to cyclic (or fluctuating) stress.
