CALCULATION OF DYNAMIC FRACTURE TOUGHNESS FOR SMALL SECTIONS

ERMITTLUNG DYNAMISCHER RISSZAEHIGKEITSWERTE AN KLEINEN QUERSCHNITTEN

Ten carbon and low alloy steels with tensile strengths of 400 to 1140 N/sq mm were subjected to notch bar impact bending tests at 20 to - 195 C. Specimens with DVM, ISO-V, and sharp notches were used. Energy values causing the first appearance of a crystalline spot and the dynamic fracture toughness KD were calculated from the results. The values obtained decreased in magnitude from DVM to ISO-V to sharp-notch specimens. With all specimens, KD values at low temperatures were approximately proportional to room temperature tensile strengths.
