Chapter 4, Problem 30P

The stress intensity factor K at a crack is given by $K=C\sigma \sqrt{\pi a}$where s is the far-field stress, a is the crack length, and C is a parameter that depends on the geometry of the specimen and crack. For the case of the edge crack shown in the figure. C is given by:

$C=\frac{1-(a/b)/2+0.32{(a/b)}^2}{\sqrt{1-a/b}}$

Write a script file that will print out a table of values with the ratio a/b in the first column and the corresponding parameter C in the second column. Let a/b range between 0.05 and 0.80 with increments of 0.05.
