An evaluation of analytical and numerical solutions to the single-lap joint

Abstract The mechanics of a single-lap joint subjected to tensile loading are investigated. Theoretical solutions, including the classic Goland and Reissner solution, are reviewed and examined in detail. It is observed that. despite the considerable efforts of a large number of researchers over a period of half a century, controversy and unresolved issues remain. Limitations related to theoretical treatments are identified and suggested improvements proposed. A two-dimensional geometrically nonlinear finite element analysis is performed to provide comparisons with the theoretical analyses. The discrepancies and controversies in the theories are resolved through detailed studies of the mechanics and validated through numerical analyses, and through a clarification of the definition of long and short joints. Modifications and corrections to the theories are suggested for practical application to lap joint analysis and design.
