1. (35 points)Using FEM to calculate the transverse modulus of the following unit cell.  
Assume that Ef  = 30 Msi,  f  = 0.2,  Em  = 0.5 Msi, m  = 0.34 and Vf = 0.5.   The following 
two boundary conditions should be used:  
 
Case 1:  
  
 
 
 
 
 
 
 
 
Solution: 
Use the following formula to calculate the values by FEM:
