... database containing approximately 151 shift data points for plates and 65 shift data points for welds and the NRC 177 data points database. Due to data scatter, the accuracy of the correlations is characterized by the observed (i.e., actual — predicted) mean residual error which was determined to be 17°F...

... Chevron-notched short bar fracture toughness ( K IvM per ASTM E 1304) has been correlated with plane strain fracture toughness ( K Ic or K Q per ASTM E 399 or ASTM B 645) for commercial 2124-T851, 7050-T7451, 7050-T7651, and 7475-T7351 plate. It was found that the chevron-notched and K...

.... Consequently, vane test results are dominated by the strength mobilized on the vertical plane. Therefore, it is the horizontal in-situ effective and yield stresses that predominantly control the vane shear strength. Yet, to date, vane strength correlations have been considered in terms of vertical stresses...

The level of performance is characterized by the value of CTOD at various sizes of the plastic zone as a function...

... with temperature and strain rate. A correlation between Charpy V-notch (CVN) transition temperature ( TK 28) and dynamic toughness transition temperature ( TK Id ) was established. This correlation is an extension of the one proposed previously between TK 28 and TK Ic . Assuming that fracture toughness...
