The computer codes corresponding to these two methods were also devel-oped and tested. Both programs are capable of treating thin or thick plates and shell structures. Shells with branches and cutouts can be treated. The outputs of the present computer programs are designed such that they can be easily adapted to any of the existing criteria for the strength of laminated composites. A SURVEY OF SUCH CRITERIA IS PRESENTED. (Author, modified-PL)
