dc.description.abstract | To understand how to analyze
Damage Tolerance in an aerospace component
loaded in compression one must first obtain correct
Fatigue Crack Growth curves. Once the fatigue
data curves are correct one could then move
forward to understand and develop a method that
predicts Fracture Mechanics fatigue lives for
designs with high compressive stresses. The
investigation yielded ground breaking results that
could change the Fatigue Crack Growth data
generation standard procedures governed by the
ASTM E-647. Also the proposed Design
Methodology and Application procedure defined a
method to analyze loading conditions with
compressive stresses above yield. It is
recommended the Compression Pre-Cracking
process is standardize and incorporated into the
ASTM E-647 procedure by replacing the existing
tension pre-cracking process with the proposed
Compression Pre-Cracking process. For the
Design Methodology and Application it is
recommended to validate the hand calculation
methodology with experimental results.
