Summary
Dynamic fracture analysis results from Heavy-Section Steel Technology (HSST) wide-plate crack-arrest tests are summarized. These tests relate to assessing nuclear reactor pressure vessel integrity under pressurized-thermal- shock (PTS) conditions. Computed results for five tests are compared with measurements of strain versus time, crack propagation speed, and the arrest location. Crack arrest toughness values determined by various analytical methods are compiled for test temperatures that range from mid-transition into the Charpy upper-shelf region for the test material.
