Unformatted text preview: Co., Inc., New York, NY, 1955, pg. 210, article 46. Analysis Type(s): Static Analysis (ANTYPE = 0) Element Type(s): 3-D 20-Node Structural Solid Elements (SOLID95) 3-D 20-Node Structural Solid Elements (SOLID186) Input Listing: vm148.dat Test Case A beam having a parabolic depth-to-length variation is subjected to an end load as shown. The other end is supported at a wall. Determine the deflection δ at the tip of the beam. Figure 148.1 Parabolic Beam Problem Sketch Material Properties E = 30 x 106 psi G = 1.5 x 108 psi υ = 0.0 Geometric Properties = 4 in ho = 2 in b = 0.2 in Loading F = -1000 lb Analysis Assumptions and Modeling Notes The problem is solved first using 3-D solid (SOLID95) and then using 3-D solid SOLID186 elements. A large shear modulus G is assumed (1.5 x 108) and the Poisson's ratio is taken as zero to match the theoretical assumptions. The six nodes at the top and bottom edges near the tip of element 1 are defined closer to the tip ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–327 VM148 so that the two mid-edge nodes (11 and 71) are not improperly locate...
