Lecture 30: CCA Model: Effective Axial Modulus and Poisson's Ratio
As an alternate approach, one can determine the effective axial modulus from Equation (7.204) if and are expressed in terms of unknown and divide both sides of this equation by and cross sectional area of . and are obtained along with by solving Equations (7.180), (7.202) and (7.203). These unknown constants are given in Equation (7.209).
(7.209)
The effective axial modulus for this special case is then given as
(7.210)
In this equation the fibre volume fraction is given as
from Equation (7.204) if 
and 
are expressed in terms of unknown 
and divide both sides of this equation by 
. 
by solving Equations (7.180), (7.202) and (7.203). These unknown constants are given in Equation (7.209).
