| Abstract: | The buckling and lateral vibration of orthotropic plates subject to in-plane loadings are analysed by using a refined plate bending elcmcnt with 18 cdgrees of freedom.For various orthotropic materials and principal clasticity directions,different edge conditions and in-plate force types buckling loads of square plates are computed and vibration frequencies are determined in terms of in-plane force intensity increascd from zero to the buckling foads. |
| |
| Keywords: | finite element method orthootropic plates bucking load vibration frequency |
