The Analysis and Design of Composite Material Bonded Joints under Static and Fatigue Loadings.

摘要

Extensive research was conducted providing analysis methods and design methodology for bonded joints in structures of laminated composite materials under static and fatigue loads. An analytical closed form solution was developed for stresses and deformations in the adhesive joint and the adherends,including transverse shear deformations and normal strain,adherend anisotrophy,and adhesive properties. A digital program provided rapid design and analysis;an inclusive parameter study provides trends and methodology. Static tests were developed providing shear and extensional stiffnesses and ultimate stresses of the adhesive in the joint configurations. Fatigue tests were conducted for various geometries,loadings,and adherend materials. (Author)
