  1. 1E9 Mangonel Design How Structures Fail Dr Roger P. West Department of Civil, Structural and Environmental Engineering Trinity College Dublin

  2. Failure Modes – Axial members • Tension in a cable • Axial stress • Extension leading to strain • Buckling in compression • Elastic • Plastic

  3. Failure Modes-Beams • Bending of a beam • Depth vs width • Tension and compression • Bending stress • Elastic and plastic • Brittle and ductile • Shear in a beam • Bolt failure • Plate failure

  4. Failure Modes • Torsion • Beam • Shaft • Plastic torsion • Lateral torsional buckling

  5. Failure Modes • Other modes • Cyclic - Fatigue • Impact • Corrosion • Shrinkage movement • Thermal movement • Appearance
