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