Available in PDF, EPUB and Kindle. Book excerpt: The state of the art in the stress analysis and strength prediction of adhesively bonded composite joints is presented. A generalized coordinate finite element analysis based on rectangular, cylindrical and wedge solid elements is developed and utilized for the three-dimensional analysis of composite bonded joints. The comparison of results between 2-D and 3-D bonded joint analysis tools are made and their limitations are discussed. Further, the submodeling technique available in the commercial finite element package ABAQUS is explored to study the three-dimensional stress field in the vicinity of joint edges and debond cracks. The series of bolted joint design codes BONJO developed by Lockheed are incorporated into a PC based Bolted and Bonded Joint (BBJ) design methodology. The Bolted and Bonded Joint design tool is made more informative and user-friendly through the use of Windows 95TM based Graphic User Interfaces (GUIs) fully integrated with a material database and on-line help.
