Lecture 19: Beam, Plate, and Shell Elements I

Topics: Beam, plate, and shell elements I

  • Brief review of major formulation approaches
  • The degeneration of a three-dimensional continuum to beam and shell behavior
  • Basic kinematic and static assumptions used
  • Formulation of isoparametric (degenerate) general shell elements of variable thickness for large displacements and rotations
  • Geometry and displacement interpolations
  • The nodal director vectors
  • Use of five or six nodal point degrees of freedom, theoretical considerations and practical use
  • The stress-strain law in shell analysis, transformations used at shell element integration points
  • Shell transition elements, modeling of transition zones between solids and shells, shell intersections
