Chapter 8 describes the application of the established virtual test of inserts under out-of-plane tension for the development of a novel sandwich panel joint design. The premise of this study is based on the general mechanic that the effective potting radius of the insert directly affects the core shear buckling as first damage mechanism. Increasing the potting radius increases the number of cell walls adjacent to the potting thus increasing the initial stiffness of the insert and postponing shear failure of the core. These two effects typically result in an increased overall strength of the insert configuration. This is illustrated in Figure 123.
