Instead, an initial chord modulus was defined from two points corresponding to strain levels of 0.000001 ([[epsilon=.sub.1]) and 0.00005 ([[epsilon].sub.2]) as follows:
Therefore, the initial chord modulus is assumed to be equivalent to the initial tangent modulus of cylinders in this study.
Figure 7 shows the relationship between the initial chord modulus and the standard chord modulus.
