Analysis Tools for Adhesively Bonded Composite Joints, Part 1: Higher-Order Theory

摘要

A new application of the higher-order theory to the analysis of adhesively bonded composite joints is investigated. The adhesively bonded joint problem is currently of interest to the aerospace field because of the heavy reliance on bonded composite structures in an extensive number of new aircraft designs. As such, new tools that enable the sizing of joints in the context of the overall vehicle design are being sought. Through comparison of analytical and finite element results from the literature, along with a recently developed unified analytical joint analysis methodology, it is shown that the higher-order theory is a capable tool for joint analysis that serves as a middle ground between the finite element approach and less general analytical methodologies. In Part 2 of the paper, an alternative analytical method for the three-dimensional stress analysis of composite bonded joints will be investigated.
