Question 2:
Illustrate out Hookes law and describe how it will be employed for stress – strain analysis for composites with one example.
Question 3:
Write down briefly about strengths of orthotropic lamina and discuss the experimental determination of strengths and stiffness for this.
Question 4:
Write down about the lamina stress –strain behaviour and variation in the laminate.
Question 5:
Give a description of orthotropic plates. Critically illustrate the governing vibration differential equations for laminated plates.
