AE-418 NASTRAN PROJECT NAME:_______________ GRADE:_________ Part 1: Create Finite Element Model A finite element model using FEMAP (NxNastran) of the problem stated below must be created. The *.modfem file must be uploaded into CANVAS at submission time along with the report. Part 1 of the report must include a detailed step by step procedure showing how to create the finite element model. Consider the finite element representation of a stiffened panel as shown below in Figure 1. Figure 1: Stiffened Plate Finite Element Representation The 20 x 20 inches plate is 0.1 inches thick and is clamped along all four edges. A uniform pressure equal to 0.5 psi is applied to the top of the plate. Because of the centroidal axes of the stiffeners does not coincide with the mid-plane of the plate, you will have to account for this when you define the element properties for the stiffeners. Dimensions for the I-shape stiffeners are given in Figure 2

Figure 2: General Dimensions, Boundary Conditions and Loading Based on the results of the finite element model you created provide the answers at the following loactions  Component of the displacement vector at the center of the plate: Disp X = Disp Y = Disp Z =  Axial on the stiffener at the center of the plate Axial Stress =  Plate von Mises stresses at the center of the plate (@-t/2) stress =

(@-t/2) stress = Part 2: Analytical Approximation for Stiffened Plate By looking in the literature or online find an analytical approximation solution to the response (deformations and stresses) of a stiffened panel. Clearly describe the assumptions and equations you will be using to find the analytical solutions to:  Component of the displacement vector at the center of the plate: Disp X = Disp Y = Disp Z =  Axial on the stiffener at the center of the plate Axial Stress =  Plate von Mises stresses at the center of the plate (@-t/2) stress = (@-t/2) stress = Part 3: Compare Part 1 and Part 2 Compare Part 1 and Part 2 and comment on your findings and proposed procedure to improve agreement between numerical (finite element) and analytical solutions.
