Available in PDF, EPUB and Kindle. Book excerpt: A method for determining crack-growth resistance curves previously proposed by the author is derived from fundamental relationships. Data are presented that further demonstrate the application of the method to materials having a wide range of properties. It is concluded that the use of this method results in obtaining fracture properties not previously measured directly.

Book excerpt: In this work, elastic-plastic fracture mechanics (EPFM) methods are extended to study the behavior of surface cracks. The material used is a tungsten inert gas (TIG) welded 2219-aluminum alloy, welded with 2319 weld wire. Calibration and a crack-growth test were performed. A multiple specimen R-curve technique was used. A group of specimens with the same initial crack geometry was tested to different deformation values. Several different groups were considered. Crack extension as a function of position along the crack front was determined and digitized into data files. A method to estimate values of the J integral as a function of position is presented. Local resistance curves were obtained. A parameter to characterize constraint is proposed. It is only based on the elastic solution for G. It is shown that the slopes of the resistance curves are uniquely related to the constraint parameter for all cases considered.

Download or read book Description of Stable and Unstable Crack Growth in the Elastic Plastic Regime in Terms of Jr Resistance Curves written by CE. Turner and published by . This book was released on 1979 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: A simple estimate is made of the elastic energy release rate, I, available from an elastic-plastic cracked component in terms of G and collapse load. I may be significantly greater than G from linear elastic behavior. A crack growth resistance curve is measured in terms of a J-like quantity, Jr, that is related to the plastic work absorbed by a geometry dependent factor, ?. The increment of elastic energy is compared to the increment of plastic work at constant displacement to predict the possibility of stable or unstable crack growth. Effects of machine compliance are included. Some recent results on instability, test piece size restrictions, and conventional J crack growth curves are recovered as a special case. Illustrative examples are given based on estimates of I and Jr curves measured on a low-strength structural steel for mixed mode or flat fracture with ductile micromechanism.
