Analyzing The Effect of Skin Postbuckling on General Stresses, Strains and Stability of Composite Structures

摘要

The present paper is a final technical report within the NCCW-1-233 research program (dated June 1, 1997) accomplished as a part of co-operation between United States' NASA and Russia's Goskomoboronprom in aeronautics, and continues similar NCCW-73 and NCC-1-233 programs accomplished in 1996 and 1997, respectively. The report concludes studies in two domains, 'Analyzing the effect of skin postbuckling on general stresses and strains in a composite structure' and 'Evaluating the effect of skin postbuckling behavior on general stability of a composite structure'; the work was fulfilled in compliance with NCC-1-233 requirements (as of June 1, 1997). Also, the present studies may be regarded as a partial generalization of efforts in (1, 2) conducted within the above programs in what concerns postbuckling behavior of composite structures.
