This book was released on 1983 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: A program of experimentation and analysis aimed at determining fracture instability in circumferentially cracked Type 304 stainless steel pipes in seismic or water-hammer loadings is described. Experimental work on center-cracked tension panels revealed that dynamic loading does not affect the net-section stress criterion evolved previously for Type 304 stainless steel. Full-scale tests on 100-mm-diameter (4 in.) pipes subjected to a dynamic load nevertheless indicate that a margin of safety exists beyond that predicted by the application of the net-section stress criterion. It is concluded that the finite duration of a dynamic loading together with the system compliance which allows stable crack growth beyond maximum load is primarily responsible. A J-based plastic fracture mechanics assessment based upon rate-dependent mechanical and fracture properties of the material was made and found to be consistent with this hypothesis.

This book was released on 1988 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elastic-plastic finite-element fracture mechanics analyses were conducted on 102-mm (4-in.) and 406-mm (16-in.)-nominal-diameter Type 304 stainless steel pipes containing circumferential through-wall cracks located in girth welds. The 406-mm (16-in.) pipe was analyzed for a fixed axial load combined with a monotonically increasing bending moment. The 102-mm (4-in.)-diameter pipe analysis was performed under a four-point bending load. Material J-resistance curves appropriate for each problem were used to initiate and grow the initial crack. Calculations were performed to analyze the 406-mm (16-in.) welded pipe treated as (1) a monolithic pipe entirely composed of base metal and (2) a composite of base metal and weldment. The 102-mm (4-in.) welded pipe analysis modeled the material as a composite of base metal and weldment and utilized a material J-resistance curve generated from an elastic-plastic analysis of a welded compact tension specimen. The results of the 406-mm (16-in.)-diameter pipe analysis demonstrated that the predictions of the extent of stable crack growth and the applied load at fracture instability depend on whether or not the pipe is modeled monolithically or as a composite of base metal and weldment. The 102-mm (4-in.) pipe fracture analysis, using a normalized interpretation of the material J-resistance curve, produced good agreement with corresponding experimental crack growth and deflection data.

This book was released on 1988 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was performed to evaluate the J-integral resistance curve behavior of 10-cm (4-in.) nominal pipe size Schedule 80 welded Type 304 stainless steel pipe. Tests were performed in four-point bending at 288°C (550°F) on 1219-mm (48-in.)-long pipe specimens with machined flaws contained in circumferential welds. Two flaw geometries were investigated. The first was a through-wall crack growing circumferentially (simple) and the second was a 360-deg part-through radial crack superimposed on a through-wall circumferential crack (complex). During the tests load, load line displacement, crack mouth opening displacement, and electrical potential drop across the crack mouth were monitored. Elastic compliance and direct current potential-drop (DCPD) techniques were used simultaneously to estimate crack extension during the tests. Pipes containing simple cracks had an average J-initiation of 1120 kJ/m2 (6400 in. . lb/in.2). The presence of the complex crack reduced the J-initiation level by approximately a factor of four and also reduced the apparent tearing modulus significantly as compared to pipes containing simple cracks.

Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was performed to determine the fracture resistance of 4 in. diameter circumferentially welded type 304 stainless pipe at 550 F (288 C). Two crack geometries were investigated. These were a circumferential through wall crack (simple) and circumferential through wall crack superimposed on a 360 degree radial crack on the inside diameter of the pipe (complex). Test results were analyzed using J-integral and limit load techniques. Additionally, J-integral resistance curve tests were performed on large plan size compact tension specimens for comparison with the pipe specimen results. Results of the J-integral analysis indicate that J-initiation for pipes containing simple cracks was approximately 1120 kJ/sq m (6400 in-lb/sq in) and a factor of four decrease in J-initiation was noted for pipes containing the complex crack. Good agreement was shown at J-initiation between pipe specimens containing the simple crack geometry and compact tension specimens. The accuracy of the limit load analysis was variable for pipes containing the simple crack geometry with the average predicted limit load calculated using the ASME Code flow stress being 8.7% higher than that actually attained in the tests. The calculated limit loads based on the ASME Code flow stress were conservative for the complex crack cases.
