Structural components can be exposed to extreme environmental conditions during operation over their service life. For this reason, they have to pass corresponding tests during development and certification in which they are tested for these loads. However, those tests are carried out separately, while in practice the loads occur in combination. This paper discusses the challenges arising from this, using the example of sandwich structures under combined mechanical and thermal loads and cylinder shells under combined mechanical loads. For this purpose, existing investigations, procedures and approaches are analysed, the necessity for combined testing is shown and a possible approach for a structured and reproducible procedure for testing components under combined loads is described.
