Determination of fracture toughness from sub-sized samples type of KLST
 Stratil, Luděk ; Hadraba, Hynek ; Dlouhý, Ivo
This contribution briefly describes testing performance of sub-sized three point bending specimen type KLST. The KLST specimens suffer significant the loss of constraint. Side grooving is necessary to obtain additional level of the constraint and to maintain straight crack front. Methodology for testing of the fracture toughness in ductile-to-brittle and ductile area is also described.

Constraint effect on values of fracture toughness in sub-sized three point bending geometry
 Stratil, Luděk ; Hadraba, Hynek ; Dlouhý, Ivo
This contribution briefly describes testing performance of sub-sized three point bending specimen type KLST. The KLST specimens suffer significant the loss of constraint. Side grooving is necessary to obtain additional level of the constraint and to maintain straight crack front. Methodology for testing of the fracture toughness in ductile-to-brittle and ductile area is also described. In certain testing conditions KLST specimens shows results comparable with standard test specimens.
