Structural Failure

Structural failure occurs when a structure permanently suffers a decrease in strength/operational capacity, unacceptable deflection, or catastrophic collapse which renders it unsuitable for its purpose. There are four typical methods;

  1. Exceeding the yield strength of a material (compressive/tension)
  2. Buckling (compression or non-axial loadings of pillars or stiffened panels)
  3. Fatigue fracture (frequent cyclical loadings above a materials fatigue limit)
  4. Brittle fracture (Tensile loadings, particularly in cold)
