Experimental Investigation on Static and Free Vibration Behavior of Concentrically Stiffened Plates
Experimental investigation and simulation study of different types of concentrically stiffened plates under static and dynamic conditions are accomplished in the present paper with an objective to establish the static deflection and natural frequency characteristics under loading. One unstiffened plate and five types of concentrically stiffened plate specimens are experimented upon in the laboratory with the help a specialized setup that simulates clamped end condition at the plate edges. There is provision for pneumatic application of transverse uniformly distributed load. The above-mentioned plate specimens are categorized on the basis of number and arrangement of the concentric stiffeners on the plate face. Finite element simulation is also performed through commercial software ANSYS Mechanical APDL 15.0 for independent validation and comparison of experimental data. Load–deflection plots and backbone curves in non-dimensional planes are presented as results.
