Book Synopsis Automated Test Methods for Fatigue Crack Growth and Fracture Toughness Tests on Irradiated Stainless Steels at High Temperature by : BAJ Schaap
Download or read book Automated Test Methods for Fatigue Crack Growth and Fracture Toughness Tests on Irradiated Stainless Steels at High Temperature written by BAJ Schaap and published by . This book was released on 1985 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: An automated system for fatigue crack growth and fracture toughness measurements has been developed for irradiated stainless steels tested at temperatures up to 925 K. The system, including a microcomputer, is based on the d-c potential-drop technique for crack extension measurements. Specimens of the compact-tension type are used for the experiments. A description is given of the potential-drop method and the automated data acquisition system. The method of collecting N-a data pairs is given as well as the calculation and analysis of the fatigue crack growth rate (da/dN) and stress-intensity factor (?K). The measurement of load, deflection, and crack extension data to determine the J-versus-?a curves is also discussed.

Book Synopsis A Method for Conducting Automated Fatigue Crack Initiation Tests on Fracture Mechanics Specimens by : PS. Pao
Download or read book A Method for Conducting Automated Fatigue Crack Initiation Tests on Fracture Mechanics Specimens written by PS. Pao and published by . This book was released on 2002 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue crack initiation in notched members is controlled by local strains at the notch root. A number of approaches have been developed for calculating local notch-tip stresses and strains from nominal stress and notch geometry considerations. One such approach uses the parameter ?K/?1/2, where ?K is the fracture mechanics stress intensity range and ? is the notch root radius. The parameter ?K/?1/2 has been shown to correlate with local notch-tip strain and provide a means of normalizing cycles-to-initiation, Ni, data for various notch-tip geometries. Fatigue crack growth rate specimens described in ASTM Test Method for Plane-Strain Fracture Toughness of Metallic Materials (E 399), ASTM Test Method for Measurement of Fatigue Crack Growth Rates (E 647) and elsewhere can be used for fatigue crack initiation testing if they have blunt notches. Data in the form of parameter ?K/?1/2 versus Ni has the same units as the traditional S-N curves. The advantage of having data in the form parameter parameter ?K/?1/2 versus Ni is that information is available on ?K and ? . As in all fracture mechanics testing, data obtained on one specimen geometry can be applied to a wide variety of structural geometries. This approach can be used in conjunction with commercially available software for fatigue crack growth rate testing, servohydraulic testing equipment, and modified fracture mechanics specimens to automate fatigue crack initiation testing. The combination of all of these elements represents a new test method. Results are presented for aluminum alloy 7075, where the effects of corrosion pits were studied and for titanium alloy Ti-6A1-4V, where the effects of heat treatment on initiation were studied.

Book Synopsis Sampling Rate Effects in Automated Fatigue Crack Growth Rate Testing by : JK. Donald
Download or read book Sampling Rate Effects in Automated Fatigue Crack Growth Rate Testing written by JK. Donald and published by . This book was released on 1994 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the advent of ASTM Test Method for Measurement of Fatigue Crack Growth Rates (E 647-91) and the associated annexes for nonvisual methods of monitoring crack length, there exists a need to address many aspects of the role that automation plays in generating fatigue crack growth rate data. The current ASTM standard provides primary guidance for visual methods of monitoring crack length and manual control of the test. The associated annexes provide guidance for two common nonvisual methods of monitoring crack length. Although they are good guides for both manual and automated control, they lack detail on many important considerations related to stress intensity (K) control, crack length precision, and load precision. This paper will emphasize the effect of sampling rate and resolution on crack length precision, dynamic load precision, and control. The issues will include analog-to-digital conversion resolution, digital filtering, peak reading, and multichannel phase considerations.
