This skill module provides specialized skills for Abaqus fatigue analysis, including high-cycle fatigue and low-cycle fatigue analysis. Fatigue analysis is used to predict the fatigue life of structures under cyclic loading.
skill_fatigue_high_cycle)High-cycle fatigue life prediction based on S-N curves, applicable for cyclic loads with stress levels below yield strength.
Applicable Scenarios:
Code Snippet:
# S-N curve parameters
Sf_prime = 1000.0 # Fatigue strength coefficient (MPa)
b = -0.085 # Fatigue strength exponent
Se = 200.0 # Fatigue limit (MPa)
# Basquin's equation for life calculation
# S = Sf * (2N)^b
log_2N = (log_S - log_Sf) / b
cycles_to_failure = int(10**log_2N / 2)
| Material | Sf' (MPa) | b | Se (MPa) |
|---|---|---|---|
| Steel | 1000 | -0.085 | 200 |
| Aluminum Alloy | 500 | -0.110 | 150 |
| Factor | Effect |
|---|---|
| Surface Roughness | Reduces fatigue strength |
| Size Effect | Larger sizes reduce strength |
| Load Type | Bending > Tension/Compression > Torsion |
