Question: 25 pts for a long fiberreinforced composite shown below the...

Question details

(25 pts) For a long fiber-reinforced composite shown below, the 2-3 plane is a plane of isotropy with a Youngs modulus of E2 and Poissons ratio of v23. If we further assume that the fiber in the 1 direction is very long, then the 2-3 plane is under a state of plane strain (i.e E11 0). The 2D plane-strain stress-strain relations in the 2-3 plane can be written as, σ22) [C22 C23 01(92) 023) 0 0 C44 Y23. Please express C22, and C44 in terms of the Engineering moduli E2 and v23. 3 Weak 2 Weak Strong
