Apply our accurate, reliable technology to a wide range of fatigue scenarios. 3 Reliable Durability Technology ANSYS nCode DesignLife software delivers modern, industry-proven fatigue capabilities. You can simulate all types of exposure to damage from fatigue, including: • Stress life (SN) for high-cycle fatigue • Strain life (EN) for low- and high-cycle fatigue • Crack growth • Safety factor (Dang Van) for predicting endurance limit under complex loadings • Weld analysis for spot and seam welds • Enhanced vibration analysis including PSD • Hybrid loading to combine loads (constant, transient, time series, etc.) To facilitate your workflow, we offer a number of advanced yet user-friendly capabilities for simulating large and complex models with the least amount of effort. • Python scripting for adding new or proprietary SN methods • High configurability for expert users • 64-bit versions for analyzing larger models • Automated selection of calculation method based on multi-axial stress state assessment • Critical area and hot-spot identification • Process encapsulation and integrated reporting • Standardized fatigue analysis processes to improve consistency and quality • Direct support for multi-curve stress-life and strain-life material curves and methods, such as Haigh diagrams, FKM guidelines • Single environment for test and CAE data Fatigue life simulation is based on a single static structural FEA result and an expected loading history while the part is in use. Engineers have used the ANSYS Fatigue module for simple geometries and loadings for many years. For the majority of realistic geometries and real-life loading histories, ANSYS nCode DesignLife is the ideal choice. Images show static structural results (above) and fatigue life results (right).
