4.1 Introduction
Learning Objectives:
1) Introduce to macromechanics of a laminate
Review Chapter 2 before moving to Chapter 4 and 5 as it is critical to understand the rest of the course. Cannot emphasize it enough.
- Do you know how to relate stress and strain for unidirectional lamina?
- Do you know how to relate stress and strain for angle lamina?
- Do you know how to go back and forth between global and local stresses?
- Do you know how to go back and forth between global and local strains?
- Do you know how to calculate elastic moduli of angle lamina?
- Do you know how to apply the four failure theories to an angle lamina?
- Do you know how to calculate coefficient of thermal expansion for an angle lamina?
- Do you know how to calculate coefficient of moisture expansion for an angle lamina?
