FEA Programs Available as Shareware

Please send me a request for explanation or questions at bikila_97@yahoo.com and I will get back to you within about 24 hours. My interest is to see these programs get used by as many people as possible. All programs run on Win95/98/NT.

  1. COSHELL :- For linear stress, linearized buckling, natural vibration, nonlinear and post-buckling analysis of stiffened composite
    cylindrical shells using the Layerwise Shell Theory. Modified Riks method used in postbuckling algorithm.

Code by :- SK, Virginia Polytechnic Institute and State Univ. Blacksburg, VA, 12/1992. Updated in 1993. Code Features: True Dynamic Array Dimensioning Implemented.
Problems of any size could be solved.The only limitation will be the available core and virtual memory of the hardware used.
Note:

The following paper provides good introduction to what COSHELL does. “Local Behavior of Discretely Stiffened Composite Plates and Cylindrical Shells,” (with J.N. Reddy), Composite Structures 41, 1998, pp. 13-26. (download copy of paper in pdf format).
