30. The stress intensity factor K at a crack is given by K=Cona where o is the far-field stress, a is the crack length, and C is a parameter that depends on the geome- try of the specimen and crack. For the case of the edge crack shown in the figure, C is given by: 1-(a/b)/2+0.326(a/b) 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 alb range between 0.05 and 0.80 with increments of 0.05. C= 2a 2b
