distortion energy theory.
6. Riveted and Welded joints –
Riveted joints:
Methods of riveting, types of rivet heads, types of riveted joints,
terminology, and strength of a riveted joint, efficiency of a riveted joint,
riveted joints for structural use.
Welded joints:
Advantages & disadvantages of welded joints over riveted joints, welding
processes, types of welded joints, strength of transverse fillet welded joint,
strength of parallel fillet welded joint, strength of butt joint, stresses on
welded joints, axially loaded unsymmetrical welded section, eccentrically
7. Pressure vessels:
