W. Nelson, C. L. Best, Schaum's Outline of Theory and Problems of Engineering Mechanics, Statics and Dynamics, McGraw-Hill Book Co., Inc., New York, NY, 1978, p. 336. Analysis Type(s): Explicit Dynamics with ANSYS LS-DYNA Element Type(s): Explicit 3-D Beam Elements (BEAM161) Input Listing: vme5.dat Test Case A homogeneous bar, pinned at a distance a from one end, with total length, L, is subjected to gravity loading and released from rest at an angle θ = 30° from the vertical. The rotational speed when it passes through θ = 0° is calculated and compared to an analytical expression. Figure E5.1 Pinned Bar Under Gravity Loading Problem Sketch ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 3–10 VME5 Material Properties Density = 1.0 kg/m3 Modulus of Elasticity = 10E6 N/m2 Poisson's Ratio = 0.30 Geometric Properties Constant square cross-section of 0.1 x 0.1 m2 Total Length, L = 1.0 m; a = 0.25m Loading The acceleration due to gravity is 9.8 m/s2 in the y-direction. One node is constrained in UX, UY, and UZ. All other nodes constrained only in UZ. At y = 0 UY = 0 Analysis Assumptions and Modeling Notes The material properties were selected arbitrarily. As noted in W. G. McLean, E. W. Nelson, C. L. Best, Schaum's Outline of Theory and Problems of Engineering Mechanics, Sta...
