Effect of Imperfections and Damping on the Type of Nonlinearity of Circular Plates and Shallow Spherical Shells

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, πœ” ( π‘˜ , 𝑛 ) and the amplitude π‘Ž ( 0 , 1 ) of the imperfection is made nondimensional with respect to the thickness 𝑇 ( 0 , 1 ) .
