Isodyne stress analysis of adhesively bonded symmetric joints

  • J. T. Pindera
  • G. Wang


The paper presents experimental data on the actual three-dimensional stress states produced by tensile axial forces in components of adhesively bonded symmetric joints. Stress components are determined in lamination planes and in planes at various distances from lamination planes using the methods of isodyne stress analysis.

The presented evidence shows that all three normal stress components exist in the components of a joint, and clearly vary with all three coordinates aligned with the length, width, and thickness of the joint. The stress state is pronounceably three dimensional and as such cannot be reliably determined using the analytical and experimental procedures based on the concept of generalized plane stress state. Thus the convenient simplified analytical and experimental procedures of stress analysis should be carefully tested for their admissibility, using as a criterion, the magnitude of acceptable error. The paper illustrates capacity of the method of analytical and optical isodynes.
