We have developed
our own Fatigue Program, using either the Strain Life or Modified Goodman
approach. We can cue directional, principal or signed Von-mises stress
components.
-
MEAN STRESS EFFECTS:
GOODMAN & HAIGH Diagrams, Design Charts
-
LOW-CYCLE FATIGUE:
Neuber Notch Strain Analysis and Strain Life Analysis
-
DAMAGE ACCUMULATION:
Linear And Non-Linear, Miner Rule
-
LOAD SPECTRUM
DEVELOPMENT: Sequence Effects, Truncation, Clipping, Retardation
-
VIBRATION AND SPECTRAL
DESITY ANALYSIS: Modal, Harmonic PSD random and Seismic vibration.
-
CRACK INITIATION: S-N
CURVES, Endurance Limit and Fatigue Strength Surface & Size effects
-
STRESS CONCENTRATION:
Data, Load Streamlines Analogy
-
FRACTURE MECHANICS
-
SOFTWARE: We have
several in-house and commercial software for Fatigue Analysis.
