Figure 10 Overview and classification of different sandwich insert types
There are no standardized tests for determining the mechanical strength of inserts and
sandwich joints in general [Mun15]. However, in case of out-of-plane tension of sandwich inserts, there is a great number of studies in the literature, which all apply the same
test setup. This setup follows suggestions given in the IDH [ESA11], which can be considered as quasi-standard. In case of shear loading, there are less examples in the literature,
however the IDH also gives guidance for this test setup. The present work follows the
IDH in both cases. More details on the implemented test setups are given in section 6,
which covers the experimental investigation of sandwich panel joints.
