Values of the normalized amplitude of the maximum dynamic stress, I I^naxl' 

 were calculated for four ranges of nondimensional frequency, U)'. The ranges were 

 as follows: 



■n/5 ^ co' ^ 7. On in increments of 1T/5 



ff/lO £ to' s 1.477 in increments of 7t/10 



^ oo' ^ Tt/2 in increments of Tt/IO 



$ co' ^ 0. 10 in increments of 0.01 



The specific values of ji used in the computations were 0.005, 0.01, 0.03, 

 0.05, 0.10, 0.50, 1.00, 2.00, and 5.00. For low ranges of co', additional values 

 of /i were used as shown on the appropriate graphs. At each value of /i, calculations 

 were performed for ^ = 0.10, 0.30, 0.50, 0.70, 1.00, 3.00, 5.00, and 7. 00 over 

 the two higher ranges of to', and values of iS = 0.25, 0.50, 1.00, 3.00, 5.00, and 

 7.00 over the two lower ranges of co'. The results of these computations are presented 

 in Figures 2 through 7 for the lowest range of to' and in Figures 8 through 13 for the 

 second lowest range. For the range ir/lO ^ to' ^ 1.477, it was found that the stress 

 calculated at values of to' near 77 were zero. Figure 14 illustrates this discontinuity. 

 In order to investigate this behavior. Equations 7, 8, 9, and 10 were combined and 

 evaluated as to' approached n 77, where n = 1, 2, 3, . . . Details of this evaluation 

 are given in Appendix B, the result being given in the form
