Blevins, Formulas for Natural Frequency and Mode Shape, Van Nostrand Reinhold Co., New York, NY, 1979, Tables 8-1 and 8-16. Analysis Type(s): Mode-frequency analysis (ANTYPE = 2) Element Type(s): 2-D 6-Nnode Triangular Structural Solid Elements (PLANE2) 2-D Structural Solid Elements (PLANE42) 2-D 8-Node Structural Solid Elements (PLANE82) 3-D Structural Solid Elements (SOLID45) 3-D 10-Node Tetrahedral Structural Solid Elements (SOLID92) 3-D 20-Node Structural Solid Elements (SOLID95) Input Listing: vmd3.dat Test Case A free-free solid beam is analyzed to determine the first axial and bending mode natural frequencies. For the axial mode case use Householder eigenvalue extraction and for the bending mode case use subspace eigenvalue extraction to extract the required eigenvalues. Examine the influence of rectangular, trapezoidal, and parallelogram element...
