In many structures and components cracks, which are exposed to a 3D-mixed-mode-loading, occur\uddue to multiaxial loading situation. A reliable evaluation of those components requires fracture mechanical\udcriteria validated by experimental investigations. Within this article 3D-mixed-mode criteria for static as well as\udcyclic loadings will be presented. Experiments for pure mode I-loading, pure mode II-loading, pure mode IIIloading\udand 2D- as well as 3D-mixed-mode-loading combinations are performed using specially developed\udspecimens and loading devices. By comparing the experimental results with criteria a widely validity of criteria\udand a generally conservative behaviour are revealed
