Plastics as a family of materials have been exceedingly used for product design.Designing with the plastic materials is generally not so straightforward as steels and aluminum. Due to the dependency of material properties on various factors.This course is an attempt to collate the important considerations when designing with plastic materials. Topics covered: 1. What are polymers and plastics2. Difference between thermo plastics and Thermosets 3. Difference between amorphous and crystalline types4. The advantages and disadvantages of using plastics for design5. Importance of data and tests - Design approach6. Mechanical behaviour - Stress strain diagram7. Flexibility, rigidity, Ductile vs brittle behaviour, Linear and Non linear behaviour8. Yield point and Elongation9. Glass transition temperature and its importance10. Visco elastic behaviour - Models11. Phenomenon of Creep and how it takes place12. Creep rupture definition 13. Behaviur in Fatigue and Fracture toughness compared to steel14. Impact toughness and which plastics are superior compared to others? 15. Hardness property and its measurement , importance16. Abrasion and Friction properties. Plastics which are good selection for anti friction applications17. What are re-inforced plastics. Their impact and Anisotropy18. Designing plastics within the larger Design process. Steps to consider, checks to include. 19. Material selection guide and factors to consider when selecting apt material20. Dimensional stability, tolerances21. Design for Injection moldingThis course is designed to aid Design engineers in the Plastics product design activity. To go beyond CAD skills and develop holistic fundamental understanding of behaviour of plastics. Helping to make better material decisions and design decisions.
