  1. Materialsselection Practical workshops: Session 1 Henri-Michel Montrieux (hmmontrieux@ulg.ac.be)

  2. Content • Introduction • MaterialsSelection for Bicycles • MaterialsSelection for Springs • MaterialsSelection for Car Radiator • MaterialsSelection for Springs • StartingwithCES

  3. Introduction • (Fracture) Toughness IS Unit? Physical aspect? Lower value of Kc?

  4. Introduction

  5. Introduction What are materialswith the best Kc/Re and Kc²/Re ratio? When do we use respectivelyKc/E and Kc²/E ? • Consequence

  6. Materialsselection for bicycles • Beams • Wheel spokes

  7. Materialsselection for bicycles (beams) • Generally: Bending, shearing, compression, tension and torsion elements. • Here, simplifiedhypothesis: bending tubes only

  8. Materialsselection for springs • Store elasticenergy

  9. Materialsselection for radiators • Car radiator • House radiator

  10. Materialsselection for radiators • Objectif : Conduire la chaleur efficacement à travers les ailettes (longueur L, section S) • Loi constitutive :

  11. Materialsselection for car radiators • Objective: Minimise mass

  12. Materialsselection for car radiators (house) • Incl. cost

  13. StartingwithCES • Simple exercise (group of 2 students)
