This resource by Dr. Roger P. West from Trinity College Dublin presents an in-depth analysis of various failure modes in structural engineering. It covers the behavior of axial members under tension and compression, exploring critical concepts such as axial stress, strain, and buckling. Additionally, it delves into beam failure, discussing bending, shear, and the distinctions between elastic and plastic failure. The presentation also addresses less common failure modes, including torsion, fatigue, and environmental impacts like corrosion and thermal movements, essential for understanding structural integrity.

Failure Modes – Axial members • Tension in a cable • Axial stress • Extension leading to strain • Buckling in compression • Elastic • Plastic
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
Failure Modes • Torsion • Beam • Shaft • Plastic torsion • Lateral torsional buckling
Failure Modes • Other modes • Cyclic - Fatigue • Impact • Corrosion • Shrinkage movement • Thermal movement • Appearance
