Example 10, Slide 10: GENOPT/BIGBOSOR4 vibration modes in which shell deformation predominates

Fig. 4 from the 2013 GENOPT paper2.(continued) Two more vibration modes from GENOPT/BIGBOSOR4 for the optimized propellant tank with one skirt attached at the midlength of the cylindrical part of the tank. These are both primarily shell deformation modes. (E) Shell deformation with n = 2 circumferential waves (ovalization of the propellant tank; (F) Shell deformation with n = 3 circumferential waves. Compare with predictions from STAGS shown in Figs.5a,b
