FORMICA GIOVANNI
(syllabus)
Contents
- provide basics knowledge in structural mechanics, focusing on both rigid and elastic bodies
- introduce students to the study and learning skills required for the analysis of simple structures (beams, frames, trusses, cables and arches), using the most commonly adopted models in structural mechanics
Program
Algebra and vector geometry (follow-up)
Force and moment distributions
Mechanics of rigid systems in 2D
- linearized kinematics
- (internal and external) constraints
- equilibrium and reaction forces
- the principle of virtual work (PVW)
Mechanics of elastic beam systems in 2D
- beam equilibrium equations
- evaluation and diagrams of internal forces
- equilibrium in truss systems
- stress and strain (outline and definition)
- construction materials: steel, basic production processes, experimental evidences (tensile test), notes on safety assessment analysis
- linear elastic behavior: relationships of stress-strain and force-displacements
- straight beam:
axial and bending behavior
basic design criteria for trusses and frames
- internal work and PVW
Complements
- cables and arches
- statically indeterminate beams
- shear stress: Jourawski formula
- notes on the elastic-plastic behavior
- notes on structural stability: Eulerian critical load and column design
