| Abstract: | The two-way multi-stiffened plate was simplifies by an orthotropic plate model.By deriving the equilibrium equation in dimensionless form and using the bending results of isotropic plate,the maximum stress was determined for the two-way multi-stiffened plates.Detailed analysis of the strength was carried out to five patterns of stiffened plates in two styles and different dimensions.The numerical results showed that the presented formula could forecast the stress of the plate accurately. |
