STABILITY, BEHAVIOUR AND VIBRATIONS OF AN ANNULAR PLATE UNDER UNIFORM COMPRESSION

The behavior of an annular plate, free at its inner edge and simply supported at the outer one is experimentally investigated. A compressive inplane force is applied uniformly at the outer boundary. Deformations, strains frequencies, and mode shapes are explored over sub, trans, and post buckling regions. Experimental results for the buckling loads are compared. An approximate formula for the vibrations of the loaded annular plates is developed and compared with the experimental results. Good agreement is found between theory and experiments. The influence of initial geometrical imperfections on the behavior of the compressed plate is discussed. (Author)
