Automated test methods for fracture and fatigue crack growth

Book ·
OSTI ID:5341003
The topics of fatigue and fatigue crack growth testing systems and of fracture testing systems are presented, including papers on new developments in automated materials testing systems, development of an automated fatigue crack propagation test, crack shape monitoring using ac field measurements, a low-cost microprocessor-based data acquisition and control system for fatigue crack growth testing, and an automatic fatigue crack monitoring system and its application to corrosion fatigue. Consideration is given to potential-drop monitoring of cracks in surface-flawed specimens, a microprocessor-based system for determining near-threshold fatigue crack growth rates, Krak-gages for automated fatigue crack growth rate testing, automated test methods for fatigue crack growth and fracture toughness tests on irradiated stainless steels at high temperature. Additional papers include an automated method of computer-controlled low-cycle fatigue crack growth testing using the elastic-plastic parameter, automated technique for R-curve testing and analysis, a computer-interactive system for elastic-plastic fracture toughness testing, and computerized single-specimen J-R curve determination for compact tension and three-point bend specimens.
