Machine elements and joining methods

Basic functions of machines and machine elements and their mechanical integrity. This includes, but not limited to:

• 2D/3D stresses and failure criteria
• Static indeterminate structures
• Mechanisms and transmissions: Mechanics of the screw, gears.
• Couplings and brakes: Disc break , drum brake (internal and external), fixed and releasable couplings.
• Bearings: roller bearings, bearing design, life time assessment.
• Springs: torsion, coil, leaf, ring and rubber springs.
• Press and shrink-fit connections: deformation of thick-walled tubes, tolerances and fits.
• Bolts: threads, load carrying capacity, pretension, tightening/torque moment, bolt diagram.
• Welded joints: static and fatigue analyses.
