Structural and Free Vibration Analysis of Stiffened Plate with Different Materials

In the current era the expanding interest of fundamentally productive and essentially exemplary quality to weight proportion are for the most part served by hardened plates. These basic components are characterized as the plates fortified by Stiffeners or set of bars or ribs one or both sides of the plate. So Stiffened plates are comprised of plate components, to which for the most part load is connected, and shaft components situated at discrete dispersion’s in one or both headings. The present investigation manages limited component examination of Stiffened plate by different Materials. The current investigation covering structural and modal analysis of stiffened plate with steel, Unidirectional Composite material as Single ply and laminated composite material with 5 plies. The Finite element Analysis is carried by using FEM Solver Optistruct which is inbuilt in Hypermesh.Optimization of results carried out to match the stiffness and natural frequencies with steel to substitute it.
