| Abstract: | A distribution of the linear in-plane forces for each element of orthotropic plates with cutouts subjected to in-plane loadings is presented by using a 6-nodes triagular planc element.After that the buckling and lateral vibration of the plates are analyzed by means of high-precision plate bending element.Thereby the effect of the size of cutout,the material property,the principal elasticity direction,the edge condition and in-plane loading type on the buckling loads and the natural frequencies is determined. |

| Keywords: | orthotropic plates finite element method buckling load vibration frequency |
