Abstract (EN): This work deals with the influence of the ratio crack length/specimen width (a/W) on crack opening displacement (COD) tests. A series of tests was performed on a weldable quality structural steel (50D, BS4360), where the ratio a/W was varied from about 0. 2 to 0. 8, keeping W constant. The influence of temperature was assessed by a series of tests at different temperatures over the range -90 degree C to room temperature. It is concluded that critical COD, delta //c, is insensitive to a/W at low temperatures, but becomes dependent on a/W as temperatures approach the transition temperature.
