✦ Synopsis

The parametric instability behaviour of curved panels with cutouts subjected to in-plane static and periodic compressive edge loadings are studied using "nite element analysis. The "rst order shear deformation theory is used to model the curved panels, considering the e!ects of transverse shear deformation and rotary inertia. The theory used is the extension of dynamic, shear deformable theory according to Sanders' "rst approximation for doubly curved shells, which can be reduced to Love's and Donnell's theories by means of tracers. The e!ects of static and dynamic load factors, geometry, boundary conditions and the cutout parameters on the principal instability regions of curved panels with cutouts are studied in detail using Bolotin's method. Quantitative results are presented to show the e!ects of shell geometry and load parameters on the stability boundaries. Results for plates are also presented as special cases and are compared with those available in the literature.
