Timoshenko, Strength of Material, Part II, Elementary Theory and Problems, 3rd Edition, D. Van Nostrand Co., Inc., New York, NY, 1956, pg. 148, article 29. Analysis Type(s): Buckling Analysis (ANTYPE = 1) Static (Prestress) Analysis (ANTYPE = 0) Element Type(s): 2-D Structural Solid Elements (PLANE42) Input Listing: vm128.dat Test Case Determine the critical buckling load of an axially loaded long slender bar of length has a cross-sectional height h, and area A. with hinged ends. The bar Figure 128.1 Buckling Bar Problem Sketch Material Properties E = 30 x 106 psi Geometric Properties = 200 in A = 0.25 in 2 h = 0.5 in Loading F = 1 lb Analysis Assumptions and Modeling Notes Only the upper half of the bar is modeled because of symmetry. The boundary conditions become free-fixed for the half symmetry model. The bar is assumed to have a rectangular cross-section (thickness = A/h = 0.5 in). AN...
