Unformatted text preview: the top centroidal locations of element 1 (near inner edge) and element 6 (near outer edge). Figure 39.1 Circular Plate Problem Sketch ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–95 VM39 Material Properties E = 30 x 106 psi υ = .3 Geometric Properties a = 30 in b = 10 in t = .25 in Θ = 105 Loading Ma = 10 in-lb/in = 52.360 in-lb/10° segment Analysis Assumptions and Modeling Notes Since the problem is axisymmetric only a small sector of elements is needed. A small angle Θ = 10° is used for approximating the circular boundary with a straight-edged element. A radial grid with nonuniform (3:1) spacing is used. The calculated load is equally divided and applied to the outer nodes.
