摘要
Abstract
Based on the diagonal tension theory of metal structure, considered the characteristics of the composite structure, induced some hypothesis, presented a post buckling method for composite wing spar, and compared with the test result of medium thickness composite wing spar about 4mm. The results showed that, the stress distribution and the invalidation load for the composite wing spar can be forecast by the method. The method makes up the deifciency of post buckling calculation for the composite wing spar.关键词
