Figure 2: (a) Three-dimensional view and (b) cross-section of the circular plate with geometric imperfection having the shape of the first axisymmetric mode. As nondimensional quantities are used, 𝜔 ( 𝑘 , 𝑛 ) and the amplitude 𝑎 ( 0 , 1 ) of the imperfection is made nondimensional with respect to the thickness 𝑇 ( 0 , 1 ) .
