Fatigue
Testing, Diagnostics, and Analysis
Many critical components see repeated cyclical loading during use. Although each load cycle remains below the static yield strength, fatigue can occur from progressive localized damage from fluctuating material stresses and strains. Unexpected and potentially catastrophic fatigue failures may result.
ES3 staff perform cutting edge finite element based fatigue analysis and simulation using nCode to support all new component designs/redesigns as well as predict failures for aircraft integrity and prognostic evaluations.
