Unformatted text preview: ar plate is found using the formula presented in Table 11-2: 1 2 Eh3 λ f= 2πa2 12γ(1 − υ2 ) 2 Where, λ2 = 4.80 In ANSYS, a 30° symmetric sector of the annular plate is created via CYCLIC expansion with CYCOPT, NODDIA. The outer edge of the model is constrained in all directions and no dampening or loading is applied. The element types SOLID185, SOLID186, SOLID187, and SHELL181 are used to solve for the lower bound of the fundamental natural frequency (Hz).
