9.4 COMPUTER IMPLEMENTATION OF FEM–sfeap

In order to illustrate computer implementation of FEM, simplified Finite Element Analysis Program (sfeap) has been developed in FORTRAN language. Following different elements have been incorporated in the program.

  1. 2-node axial bar/plane truss element
  2. 2-node space truss element
  3. 2-node beam/plane frame element
  4. CST element for two-dimensional stress analysis
  5. 3- to 9-node element for two-dimensional stress analysis
  6. Axi-symmetric isoparametric element for axi-symmetric load (Circumferential harmonic = 0)
  7. Axi-symmetric isoparametric element for asymmetrical load (Circumferential harmonic > 0)
  8. 8-node isoparametric element for three-dimensional stress analysis

In addition, few dummy routines are kept, which ...
