Download or read book Automated Measurement of Crack Length and Load Line Displacement at Elevated Temperature written by H. P. van Leeuwen and published by . This book was released on 1988 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Test results in the literature show that, in creep cracking tests at elevated temperature under steady load, the crack growth rate correlates best with the contour integral C, also called J*, in comparison to other possible parameters. In the case of the fatigue at elevated temperature, the crack growth rate correlates best with C* if cracking is predominantly time dependent. If, however, cracking is predominantly cycle dependent the crack growth rate correlates best with the range delta J of the contour integral J. It is discussed that in such testing C* and J are fairly easily determined if, apart from load and crack length, the load line displacement is measured. A description is given of a test set-up developed for elevated temperature creep cracking tests in which crack length was measured with the electrical potential drop method and load line displacement was measured with two inductive transducers located inside the furnace. Measurement was automated with the aid of a personal compute which controlled the measurements and processed the results automatically. This set-up can be adapted for elevated temperature fatigue testing. Keywords: Creep tests; Crack propagation; High temperatures; Automatic control; Fatigue tests.

Download or read book High Temperature Aluminides and Intermetallics written by S.H. Whang and published by Elsevier. This book was released on 2013-10-22 with total page 759 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of proceedings is concerned with an increasingly important area, that of intermetallics and high temperature aluminides, which has recently been attracting a great deal of attention. Nearly 150 papers presented at the meeting held in San Diego in September 1991 are reproduced here. They cover a wide range of related topics such as the bonding characteristic and alloying behaviour of TiA1 intermetallic compounds and the cleavage fracture of ordered intermetallic alloys. All the papers have been reviewed according to the standards set by Materials Science and Engineering. This book will be of interest to metallurgists and materials scientists working with composites who are interested in the latest developments in this fast–moving field.

Download or read book Use of Services for Family Planning and Infertility United States 1982 written by Gerry E. Hendershot and published by . This book was released on 1988 with total page 982 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1982 statistics on the use of family planning and infertility services presented in this report are preliminary results from Cycle III of the National Survey of Family Growth (NSFG), conducted by the National Center for Health Statistics. Data were collected through personal interviews with a multistage area probability sample of 7969 women aged 15-44. A detailed series of questions was asked to obtain relatively complete estimates of the extent and type of family planning services received. Statistics on family planning services are limited to women who were able to conceive 3 years before the interview date. Overall, 79% of currently mrried nonsterile women reported using some type of family planning service during the previous 3 years. There were no statistically significant differences between white (79%), black (75%) or Hispanic (77%) wives, or between the 2 income groups. The 1982 survey questions were more comprehensive than those of earlier cycles of the survey. The annual rate of visits for family planning services in 1982 was 1077 visits /1000 women. Teenagers had the highest annual visit rate (1581/1000) of any age group for all sources of family planning services combined. Visit rates declined sharply with age from 1447 at ages 15-24 to 479 at ages 35-44. Similar declines with age also were found in the visit rates for white and black women separately. Nevertheless, the annual visit rate for black women (1334/1000) was significantly higher than that for white women (1033). The highest overall visit rate was for black women 15-19 years of age (1867/1000). Nearly 2/3 of all family planning visits were to private medical sources. Teenagers of all races had higher family planning service visit rates to clinics than to private medical sources, as did black women age 15-24. White women age 20 and older had higher visit rates to private medical services than to clinics. Never married women had higher visit rates to clinics than currently or formerly married women. Data were also collected in 1982 on use of medical services for infertility by women who had difficulty in conceiving or carrying a pregnancy to term. About 1 million ever married women had 1 or more infertility visits in the 12 months before the interview. During the 3 years before interview, about 1.9 million women had infertility visits. For all ever married women, as well as for white and black women separately, infertility services were more likely to be secured from private medical sources than from clinics. The survey design, reliability of the estimates and the terms used are explained in the technical notes.
