Unformatted text preview: f Solids, McGrawHill Book Co., Inc., New York, NY, 1959, pg. 234, problem 5.31. Analysis Type(s): Static, Plastic Analysis (ANTYPE = 0) Element Type(s): 2-D Spar (or Truss) Elements (LINK1) Input Listing: vm11.dat Test Case A chain hoist is attached to the ceiling through three tie rods as shown below. The tie rods are made of coldrolled steel with yield strength σyp and each has an area A. Find the deflection δ at load F1 when the deflections are elastic in all three rods. When the frame is loaded to F2 (where all three rods become fully plastic), and then unloaded, find the residual stress σr in the central rod. Figure 11.1 Residual Stress Problem Sketch Material Properties σyp = 30,000 psi Geometric Properties A = 1 in2 E = 30 x 106 psi = 100 in Θ = 30° Loading F1 = 51,961.5 lb F2 = 81,961.5 lb Note — F1 and F2 values are back-calculated from theoretical relationships. Analysis Assumptions and Modeling Notes Automatic load stepping (AUTOTS,ON) is used to obtain the nonlinear plastic solution (load steps 2 and 3). ANSYS Verification Manual . ANSYS...
