7 Virtual testing approach for sandwich panel joints
This chapter describes the developed approach for virtual testing of sandwich panel
joints using the sub-component tests of chapter 6 as example and for validation. The
investigations in chapter 4 and 5 are integral parts of this approach. Therefore, aspects
of these chapters are revisited and put into perspective of the approach. In the following,
an overview over the approach and it’s four phases is given in section 7.1. Then each
phase is described in section 7.2, 7.3, 7.4 and 7.5 using a demonstration example. Sections 7.6 and 7.7 summarize and conclude with additional case studies as validation.
7.1 Overview
The approach is based on the premise, that there is a reference physical test, which represents the top level of the building block pyramid in the investigated scope. It is assumed that measurement results and documentation of the reference test are available
based on a reference test article. In order to implement a virtual test method, which can
replace or complement the physical test, the virtual testing approach suggests four
phases which are schematically illustrated in Figure 78.
