Content • Introduction • MaterialsSelection for Bicycles • MaterialsSelection for Springs • MaterialsSelection for Car Radiator • MaterialsSelection for Springs • StartingwithCES
Introduction • (Fracture) Toughness IS Unit? Physical aspect? Lower value of Kc?
Introduction What are materialswith the best Kc/Re and Kc²/Re ratio? When do we use respectivelyKc/E and Kc²/E ? • Consequence
Materialsselection for bicycles • Beams • Wheel spokes
Materialsselection for bicycles (beams) • Generally: Bending, shearing, compression, tension and torsion elements. • Here, simplifiedhypothesis: bending tubes only
Materialsselection for springs • Store elasticenergy
Materialsselection for radiators • Car radiator • House radiator
Materialsselection for radiators • Objectif : Conduire la chaleur efficacement à travers les ailettes (longueur L, section S) • Loi constitutive :
Materialsselection for car radiators • Objective: Minimise mass
Materialsselection for car radiators (house) • Incl. cost
StartingwithCES • Simple exercise (group of 2 students)
