AE304 ANSYS Tutorial: Creating a Wing Box using Shell & Beam Elements Problem : A cantilevered idealized wing box made of Aluminum alloy with the Elastic modulus of E = 10.6 10 6 psi and Poisson’s ratio ν = 0.33 is subjected to a load as shown in figure below. All dimensions are in inches. The thickness of the bottom and top skins is 0.05 in and the thickness of the webs is 0.07 in. The skins and webs will be modeled using SHELL63 element (shell element with 4 nodes) and the stringers will be modeled using BEAM188 of circular cross-section. 500 lb 500 lb x y z 1 2 3 4 5 6 7 8 150 32 20 16 Stringer Area (in 2 ) 1, 41 2, 31 . 2 Create input file: using keypoints /title, Wing Box /prep7 k, 1, 0, 0, 20 k, 2, 32, 0, 20 k, 3, 32, 0, 4 k, 4, 0, 0, 0 k, 5, 0, 150, 20 k, 6, 32, 150, 20 k, 7, 32, 150, 4 k, 8, 0, 150, 0 finish Starts ANSYS: Under File pull-down menu: - Change Jobname: ‘ yourfilename - Change Directory: ‘P’ drive folder Under Preprocessing: - Add Element Types: ‘Shell63’ & ‘Beam188’ - Add Real Constant Sets for Shell63: Set 1: Input 0.05 for shell thickness at nodes i, j, k, and l Set 2: Input 0.07 - Add Material Properties: - Material Models - Structural - Linear - Elastic
