| Abstract: | Based on the differential equation of the nonlinear bending of shallow spherical shells with variable thickness under axisymmetrical loads, this papsr studies the numerical solution of the nonlinear differential equation by means of interpolating matrix method, The analysis of the results indicates that the suggested method is easy to implement and obtains the same high accuracy for both the displacements and the internal forces. |
