  1. The mystery of life is not a problem to be solved, but a reality to be experienced - Meditations from Buddislamic Text

  2. Mechanical properties Tensile test Hardness Toughness Fracture toughness Fatigue test Creep resistance

  3. Tensile test Yield strength Tensile strength Ductility

  4. Tensile test Yield strength Tensile strength Ductility

  5. Tensile test Yield strength Tensile strength Ductility

  6. Tensile test Yield strength Tensile strength Ductility

  7. Tensile test Yield strength Tensile strength Ductility

  8. Yield (ksi) Tensile (ksi) Elongation Steels 30-250 60-250 65-2 % For metals: in general, increase strength, decrease ductility

  9. Yield (ksi) Tensile (ksi) Elongation Steels 30-250 60-250 65-2 % Al alloys 5-80 13-90 45-4 Ni alloys 15-170 50-210 60-5

  10. Yield (ksi) Tensile (ksi) Elongation Steels 30-250 60-250 65-2 % Al alloys 5-80 13-90 45-4 Ni alloys 15-170 50-210 60-5 Ceramics - 20-380 0 Ceramics are..........?

  11. Yield (ksi) Tensile (ksi) Elongation Steels 30-250 60-250 65-2 % Al alloys 5-80 13-90 45-4 Ni alloys 15-170 50-210 60-5 Ceramics - 20-380 0 Brittle does not mean weak

  12. Yield (ksi) Tensile (ksi) Elongation Steels 30-250 60-250 65-2 % Al alloys 5-80 13-90 45-4 Ni alloys 15-170 50-210 60-5 Ceramics - 20-380 0 Thermoplastics - 1-12 5-1000 Thermosetting - 5-25 0

  13. Hardness Resistance to indentation

  14. Hardness Resistance to indentation Greater hardness gives higher hardness nos.

  15. Example - quenched plain carbon steels

  16. Correlation betwn strength & hardness Harder means stronger for metals & alloys

  17. Toughness Resistance to being clobbered

  18. Toughness Resistance to being clobbered Impact test measures energy absorbed upon fracture measure of toughness

  19. Toughness Resistance to being clobbered

  20. Impact test measure impact energy at different temperatures

  21. Impact test measure impact energy at different temperatures

  22. Impact test measure impact energy at different temperatures

  23. Assignments for next class: 1. review today's classnotes; know tensile test & what data obtained, hardness test, impact test 2. Do problems previously assigned on ANGEL (use Matweb for data)
