In this study, the deformation of circular thin plates subjected to a uniformly distributed load is investigated because the critical deflection, stress, and strain values of circular plates under loads have an important role in the design criteria. For this purpose, two models of circular plates were presented and their static analysis was studied. Static analysis has been carried out for two types of plates. The first model represents the specimens that are made of isotropic material made of brass, and the second model represents the specimens that are made of an orthotropic composite material made of Carbon Fiber Reinforced Polymer. All of the models have the same boundary condition, in this way, it was easier to compare the results. The tests were conducted with a pressure system specially built for this work. It was used to measure the maximum deflection of the circular plate under uniform internal hydrostatic pressure. Numerical analysis (finite element analysis, FEA) has been carried out by developing programming in SOLID WORKS Simulation, and the results obtained from SOLID WORKS Simulation are in good agreement with the results obtained experimentally. It is found that maximum deflection for brass was 12.05 mm at 8 bar and 17.1 mm at 7 bar for carbon fiber. Finally, a comparison has been conducted between the results obtained from the FEA numerical analysis and experimental results for the two models of plates. Numerical results showed that the results obtained by finite element analysis are in close agreement with the experimental results obtained from the designed system. [ABSTRACT FROM AUTHOR]

Circular thin plates are using in a wide range of engineering applications like roof and floor of building, deck slab of bridge, water tanks, turbine disks etc. Despite that, few experimental studies have been conducted to examine the behavior of a thin circular plate under uniformly distributed loads. The present study investigates the failure behavior of uniformly loaded clamped circular thin plates experimentally. The tests are conducting with a pressure system specially built for this work. It was developed to measure the maximum deflection of the circular plate under uniform internal hydrostatic pressure. Numerical and experimental results were compared and showed a good correlation for all plates investigated. The failure mechanism is discussed based on the results of numerical calculations and the results of a scanning electronic microscope (SEM). The results observed in this study show a good understanding of the problems related to different internal pressure values. [ABSTRACT FROM AUTHOR]
