Fundamentals of Solid Mechanics

Educational Goals

The course intends to give the necessary tools for the mechanical design and structural analysis of mechanical components and systems.

Content

The course deals with the problems of the stress and strain determination in the mechanical components, the materials mechanical behaviour, the strength criteria under the action of static or cyclic loads. Such concepts are applied to the structural analysis and strength assessment of the most common machine elements.

Extended Syllabus

Recalls on stresses and strains in continuous deformable bodies.

Mechanical behaviour of materials and strength assessment under static loads.
Material charecterisation tests: tension, compression, torsion. Strength criteria for ductile and brittle behaviour, safety factor, probabilistic approach.

Notch effects
Stress concentration, notch design, plastic deformation and residual stresses

Mechanical behaviour of materials and strength assessment under cyclic loads.
Evolution of the fatigue damage and fatigue limit, influence of mean stresses, notches, dimensions, surface finishing, load frequency and waveform. Fatigue strength criteria for uniaxial and multiaxial stress states.
Miner law, random fatigue. Contact fatigue. Fatigue design: material selection, influence of thermal and mechanical treatments on the fatigue resistance of the mechanical components, notch design

Design and strength verification of typical machine components.
Welded and bolted joints, shafts, bearings, cranks and crankshafts, gears and speed reducers, pressure vessels.
