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...
