Fatigue Analysis Methodologies Supported by MSC CAEfatigue

Stress-Life (S-N) High-Cycle Fatigue Analysis

The software employs the stress-life (S-N) approach for predicting fatigue life under conditions where stresses remain largely elastic, common in high-cycle fatigue scenarios. This method utilizes material-specific S-N curves, which plot stress amplitude against the number of cycles to failure, to estimate component durability under cyclic loading.

Strain-Energy (ε-N) Low-Cycle Fatigue and Cyclic Plasticity Modeling

For low-cycle fatigue applications, where stresses may exceed the material’s yield strength leading to plastic deformation, MSC CAEfatigue utilizes the strain-life (ε-N) methodology. This approach uses strain-based fatigue curves and incorporates models for cyclic plasticity to accurately capture material behavior and predict failure in regions experiencing significant deformation.

Multi-Axial and Non-Proportional Fatigue Approaches

MSC CAEfatigue supports advanced methods for analyzing fatigue under complex multi-axial and non-proportional loading conditions. Techniques such as critical plane methods and stress invariant approaches are implemented to accurately assess fatigue damage when stress states vary in direction and magnitude throughout a loading cycle.
