Abstract
In this study, we present evaluation of stress singularity field for three-dimensional bonded joints using mesh free method. Stress singularity occurs at vertex on interface in bonded structure when external load is applied to upper surface of the structure, and it might be induced delamination or crack. Therefore, it is important to clarify intensity of stress singularity on interface to prevent destruction of bonded structure. In this study, width of bonded structure is varied, and variation of intensity of stress singularity is investigated. As a computational model, Fe and Al boned structure is employed.
