Available in PDF, EPUB and Kindle. Book excerpt: The dynamic fracture toughness of an ASTM A533, Grade B steel plate was determined at several temperatures in the ductile-brittle transition region. Crack-tip loading rates ranged from approximately 10(sup3) to 10(sup5) MPa m/s. The fracture toughness was shown to decrease with increased loading rate. The dynamic fracture toughness was compared with results from previous investigations, and it was shown that the decrease in toughness due to increased loading rate at the highest test temperature was not as severe as reported in previous investigations. It was also shown that the reference temperature. T(sub0) was better index of the fracture toughness vs. temperature relationship than the nil-ductility temperature, RT(subNDT), for this material.

This book was released on 1999 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dynamic fracture toughness of an ASTM A533, Grade B steel plate was determined at several temperatures in the ductile-brittle transition region. Crack-tip loading rates ranged from approximately 103 to 105 MPa?m/s. The fracture toughness was shown to decrease with increased loading rate. The dynamic fracture toughness was compared with results from previous investigations and it was shown that the decrease in toughness due to increased loading rate at the highest test temperature was not as severe as reported in previous investigations. It was also shown that the reference temperature, T0, was a better index of the fracture toughness vs. temperature relationship than the nil-ductility temperature, RTNDT for this material.

This book was released on 1992 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of coupled pressure bars (CPB) to induce dynamic fracture in tough materials using small specimens is investigated. CPB experiments were performed with a nuclear pressure vessel steel, A533 Grade B Class 1, over the temperature range 37 to 100°C. The dynamic fracture initiation toughness at a stress intensity loading rate, KI, of 2 x 106 MPa•m1⁄2 s-1 was deduced from the simulation of the fracture experiment with a dynamic viscoplastic finite-element fracture code. At 100°C, no cleavage fracture was observed for either dynamic crack initiation or subsequent propagation and arrest. A procedure to measure initiation, propagation, and arrest toughnesses of nuclear pressure vessel steels up to service temperature with CPB specimens is introduced.

Download or read book Dynamic Fracture Toughness of SA533 Grade A Class 2 Base Plate and Weldments written by JA. Begley and published by . This book was released on 1977 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic fracture toughness tests were performed on four base plate heats and six weldments of SA533 Gr A Cl 2 pressure vessel steel. Linear elastic KId results were obtained at low temperatures while J-integral techniques were utilized to evaluate dynamic toughness over the transition and upper shelf temperature ranges. Loading rates in terms of ?K were on the order of 2 to 4 x 104 ksi in/s(2.2to4.4x104MPam/s). Charpy and drop weight nil-ductility transition (NDT) tests were performed to permit a comparison of toughness results with the American Society of Mechanical Engineers (ASME) code reference toughness KIR curve. Dynamic instrumented precracked Charpy tests on base plate material were included for a comparison with compact toughness (CT) specimen results. All dynamic fracture-toughness values of SA533 Gr A Cl 2 base, weld, and heat affected zone (HAZ) material exceeded the ASME code reference toughness KIR curve. Fracture-toughness values obtained via small specimen dynamic JId tests (1.0 in. (2.5 cm) thick CT specimens) compared well with previously developed large specimen KId values. Dynamic instrumented precracked Charpy toughness values were also comparable at low temperatures but failed to meet minimum J specimen size limitations midway into the transition-temperature range. At this point, Charpy toughness values increased dramatically compared to JId results meeting a 25 JId/?f size criterion and, thus, should not be considered a valid representation of fracture toughness. True upper shelf dynamic fracture-toughness results are also presented. The point of crack initiation (which provides the minimum measured value of JId) was identified rather than the typical maximum load point.

Download or read book Dynamic Fracture Toughness Measurements in the Ductile-to- Brittle Region Using Small Specimens written by RE. Link and published by . This book was released on 2003 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dynamic fracture toughness of a reactor pressure vessel steel was investigated using small specimens. Precracked Charpy-size SE(B) specimens and circumferentially cracked round bars (CRB) loaded in tension were used to investigate the dynamic fracture toughness of an A533, Gr. B steel plate within the ductile-brittle transition region. The specimens used in this investigation were removed from the broken halves of conventional 4T C(T) specimens that had been utilized in a previous investigation of the dynamic fracture toughness of this material. Crack-tip loading rates in excess of 104 MPa-m1/2/s were achieved in the current tests. Multiple specimens were tested at each temperature in order to permit the determination of the reference temperature, T0. A fracture toughness scaling model for the circumferentially cracked round bar developed by Sciabetta was used to account for the loss of constraint in this specimen. A master curve approach was used to characterize the dynamic toughness in the ductile-brittle region. The shift in transition temperature was compared to a model for the strain rate dependence of T0 developed by Wallin. The shift in transition temperature of the CRB specimen was accurately predicted by the model. The CRB specimen and the dynamic SE(B) specimens gave good results considering the material inhomogeneity typical of the plate tested.
