| Abstract Scope |
In this study, a complex test stand for loading single tooth geometries is developed. The tooth geometry is exposed to cyclic loading for investigating the mechanical properties and behavior under cyclic loads.
The test specimens are thermomechanically simulated and manufactured in a specific way for the compressive residual stresses induced by the manufacturing process to counteract the operational tensile stresses. This approach aims to increase the fatigue strength of the components and minimize crack formation and fatigue phenomena.
A detailed investigation of crack and fatigue phenomena is conducted while comparing three different categories of components: LPBF-manufactured components with residual stresses, stress-relieved LPBF components and conventionally manufactured components.
The aim is to derive the potential of non-heat-treated, residual-stress-bearing components and positively utilize the superposition of residual and operational stresses. The findings on the behavior and advantages of these components under cyclic loads are evaluated to optimize their application in industrial practice. |
