Description
The indirect tension test allows the determination of tensile strength via a uniform diametric line compression of a cylindrical specimen. Using cylindrical specimens and compressing them vertically between two cylindrical seating loading jaws gives an indirect tensile stress and a corresponding orthogonal deformation. This experimental setup is also known as the Brazilian test. The apparatus is intended to be mounted on a load frame. Two versions are available, the standard ITB250 for specimen diameter up to 76-mm and the extended one for diameter up to 150-mm.
