joints. In addition, a literature review on computational modelling of sandwich structures and virtual testing approaches is presented.
The following chapters 4 to 6 are each dedicated to one of the three investigated hierarchy levels. Chapter 4 summarizes the performed experimental and numerical studies on
various sandwich structures on constituent level. This includes face sheets, core and adhesives. Chapter 5 describes the investigations on structural element level, which corresponds to the bonded sandwich panel. In both chapters, virtual testing concepts are applied to derive suitable computational models, while information is transferred between
the hierarchy levels.
In chapter 6, experimental studies on sandwich panel joints are outlined. These include
various configurations of standard potted inserts as well as mortise corner joints. These
experimental studies on sub-component level serve as basis for the development and
validation of the proposed virtual testing approach.
Chapter 7 describes the developed approach for virtual testing of sandwich panel joints
using a demonstration example. The investigations described in chapter 3 and 5 are integral part of this approach. Therefore, aspects of these chapters are revisited and put
into perspective. In addition to the described demonstration example, further validation
examples are outlined.
Chapter 8 demonstrates the application of the established virtual testing approach in an
engineering design study for the development of a novel sandwich panel joint.
