Strength of Structural Materials

Upon completion of the course, students should be able to: 1. utilise bending theory to obtain stress distribution across a bending section, as well as the slope and deflection at a section given any bending moment and shear force distribution along the beam; 2. determine whether a point in a material subjected to multidimensional stress will fail according to any failure theory; 3. explain the concepts of creep, fatigue and their implications in the use of structural materials; 4. analyse motion and stresses in springs; 5. determine the stresses and strains due to internal pressure on thin and thick cylinder walls; and 6. determine the stresses and strains induced in rotating disks and the implications.

Advanced topics on axial, lateral, and torsional loading of shafts and beams; slope and deflection of beams; unsymmetrical bending and shear centre; applications. Springs. Creep, fatigue, fracture and stress concentration. Stresses in thin and thick cylinders, and rotating disks. Multi-dimensional stress systems, Mohr's circle and failure theories.
