This page provides the introduction to experimental methods used for characterization of fracture resistance in this repository.

The Inclined Edge Cracked Semi-Circular Bend (IACSB) specimen, in comparison with others, gives the opportunity to cover a wider range of the stress intensity factors (*K _{I}* and

The IASCB specimen, shown in the figure below is a semi-circular disk of radius *R* and thickness *t* which contains a radial edge crack of length *a*, tilted with respect to the load direction of an angle α.

To conduct the fracture tests, a specimen is positioned on two bottom supports and loaded by a vertical force *P* (figure above). Different values of geometric parameters *S _{1}*,

*S*and_{1}/R*S*(the ratio between the support spans and the specimen radius);_{2}/R*a/R*(the ratio between the crack length and the specimen radius);- α (the angle between the crack line and the load direction).
