|Title:||USE OF CHEVRON V-NOTCHED SPECIMENS IN FRACTURE TOUGHNESS DETERMINATION.|

|Abstract:||The relationship between the plane strain fracture toughness, obtained in accordance with the ASTM E399-78 testing standard and the maximum load, determined from chevron-notched short bar specimens, 3-point bend rectangular specimens and 3-point bend round bar specimens has been investigated. High strength Assab 25X steel of 0. 32% C was used. The specimens were tempered from the as-quenched state to 500 degree C. Fracture toughness values calculated for the short bar specimens were found to be generally in good agreement with those obtained from the ASTM test standard when rising crack growth resistance curve was taken into consideration.|
