__FORCETOC__

==General information==

The Anglo-Saxon abbreviation SCB stands for ‘Split-Cantilever Beam’.

The SCB-specimen is used to determine the interlaminar [[Crack Toughness|crack toughness]] under [[Fracture Modes|mode]] III loading (see: [[Crack Opening Modes|crack opening modes]]).

==Testing adhesive bonds==

''(Author: Prof. Dr.-Ing. S. Marzi)''

When testing [[Adhesive Joints – Determination of Characteristic Values|adhesive bonds]], it is advisable to make the joined parts more solid due to their high [[Fracture Mechanics|fracture toughness]] [2]. Due to their similarity to [[DCB-Specimen|DCB-specimens]] (Mode I), these test specimens are called UODCB (out-of-plane loaded Double Cantilever Beam) or, in their tapered form, TODCB (tapered out-of-plane loaded Double Cantilever Beam). '''Figure 2''' shows these two basic forms of [[Specimen|test specimens]]. The same methods used for DCB and [[TDCB-Specimen|TDCB tests]] in [[Fracture Modes|mode I]] are available for evaluating the tests.
