| Abstract: | The problem of large deflection of the annular sandwich plate of variable thickness was studied.By using the shooting method and the analytical continuation method,the numerical solution of the nonlinear bending was found.In addition,we discussed the bending problem influenced by geometric and physical parameters.Finally,the characteristic curve was given as a reference for engineering designs. |
