Available in PDF, EPUB and Kindle. Book excerpt: A series of large-scale wide plate tests have been carried out on the nuclear reactor pressure vessel steel A533B to investigate the effect of biaxial loading on fracture performance at temperatures towards the lower shelf of the ductile-brittle transition. These tests have been conducted using a purpose built test rig in which a cruciform specimen is loaded so that a central region (approximately 500 mm2) experienced uniform (equibiaxial) stressing. These tests are compared to the behavior of wide plates under uniaxial loading. Small-scale three-point-bend tests have also been performed to aid the interpretation of the large-scale test results. This paper describes the experimental method and draws the following conclusions from the test results: 1. Failure conditions toward the lower shelf of toughness for equibiaxial and uniaxial loadings may be safely predicted from full thickness three-point-bend specimens. 2. The stress intensity factor (Kc) at failure would appear to be lower under equibiaxial than under uniaxial conditions. In addition, much greater plasticity (as measured by CTOD and stretch zone width) occurs in the uniaxial case. 3. Under equibiaxial conditions, preloading at + 70°C to loads at K levels which could cause final fracture at -130°C would appear to have no significant effect on the fracture performance at the low temperature.

Download or read book Evaluation of the Effect of Biaxial Loading on the To Reference Temperature Using a Cruciform Specimen Geometry written by JA. Joyce and published by . This book was released on 2005 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of 12 cruciform geometry fracture toughness specimens has recently been tested using A533B base plate obtained from the decommissioned Shoreham plant pressure vessel. Specimens were tested at -100°C, placing them in the lower ductile to brittle transition of this ferritic structural steel. The overall objective of this work is to compare the results of these biaxial cruciform tests to the results of standard and shallow crack fracture toughness tests to assess the effect of biaxial loading on the measured master curve and the To reference temperature as defined by ASTM E 1921. Previous work done at Oak Ridge National Laboratory (ORNL) appeared to demonstrate an increase in the To reference temperature due to the presence of the biaxial stress field established in the cruciform test geometry. Because of the cost of the ORNL tests, only a few specimens could be run, and full statistical support of the "biaxial effect" could not be demonstrated. A second goal is to demonstrate that smaller size specimens, and hence lower cost tests, can be used to evaluate the magnitude of the biaxial effect in nuclear reactor pressure vessel materials. This report presents a brief overview of the test procedure, presents the test results, and compares the results to the database available on standard and shallow crack fracture toughness results available for the Shoreham plate material.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this major reference work is to provide a first point of entry to the literature for the researchers in any field relating to structural integrity in the form of a definitive research/reference tool which links the various sub-disciplines that comprise the whole of structural integrity. Special emphasis will be given to the interaction between mechanics and materials and structural integrity applications. Because of the interdisciplinary and applied nature of the work, it will be of interest to mechanical engineers and materials scientists from both academic and industrial backgrounds including bioengineering, interface engineering and nanotechnology. The scope of this work encompasses, but is not restricted to: fracture mechanics, fatigue, creep, materials, dynamics, environmental degradation, numerical methods, failure mechanisms and damage mechanics, interfacial fracture and nano-technology, structural analysis, surface behaviour and heart valves. The structures under consideration include: pressure vessels and piping, off-shore structures, gas installations and pipelines, chemical plants, aircraft, railways, bridges, plates and shells, electronic circuits, interfaces, nanotechnology, artificial organs, biomaterial prostheses, cast structures, mining... and more. Case studies will form an integral part of the work.
