Book excerpt: The role of energy in the modern world goes beyond mere technology and economics to influence welfare, the environment, the quality of life and, in broad terms, civilization itself. Since the Industrial Revolution, energy conservation technology has been at the forefront of the innovation required to satisfy the needs of mankind and, more than any other, this technology has always depended on the performance of the materials used.

Download or read book The Fatigue and Static Properties of Butt Welds in Structural Steels written by L. A. Harris and published by . This book was released on 1954 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report presents the results of the first phase of a study of full scale welded joints: a study of the fatigue and static properties of butt welds. The purpose of the tests reported were to compare the fatigue and static properties of butt welds produced with the E6010 and the E7016 electrodes. Two types of butt weld specimens were tested: the longitudinal butt welds were tested with the applied stress parallel to the direction of welding, whereas the transverse butt welds were tested with the applied stress perpendicular to the direction of welding. The butt welds have been tested either with the reinforcement on or with the reinforcement removed by grinding. The specimens were subjected to a stress cycle which varied from a low tension of about 2000 psi to a maximum tension which was of such magnitude that failure generally occurred between 100,000 and 2,000,000 cycles. In order to more thoroughly understand the behaviour of butt welds subjected to repeated stresses, an extensive review of the fatigue tests of butt welds conducted previously at the University of Illinois is included in the report.

This book was released on 1955 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made to determine the fatigue and static properties of butt-welded joints in A-242 steel and to compare, quantitatively, these results with those obtained from similar joints in A-7 steel. Four types of specimens were employed in this investigation. A plain plate specimen was selected to determine the fatigue properties of the base material, a tee filletwelded joint was used to compare the fatigue properties of fillet welds deposited with E7016 electrodes on A-242 and A-7 steels, and longitudinal and transverse buttwelded joints were selected to study the fatigue and static properties of butt welds with the applied load parallel to and perpendicular to the direction of welding. All of the fatigue specimens were tested on a zero-tension stress cycle of such a magnitude that failure generally occurred between 100,000 and 2,000,000 cycles. To study the effect of surface geometry, the plain plate and butt weld specimens were tested either with the mill scale and weld reinforcement on or with all surface irregularities removed by grinding. The A-242 longitudinal butt-welded joints were found to be about 15 percent stronger under repeated loads then similar A-7 joints, whereas there was little difference between the average fatigue strengths of transverse butt-welded joints of the two steels.

Download or read book Fatigue Data Handbook written by A. Buch and published by Trans Tech Publications Ltd. This book was released on 1998-03-17 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: This authoritative handbook presents an extensive compilation of data covering all important fatigue situations - fatigue strength of steels and other materials, notch- , size-, and mean stress effects, influence of temperature and corrosion, influence of special surface treatments, fatigue of structural elements and welds, aircraft fatigue, multilevel loading test programs, fatigue performance prediction etc.As is well known, fatigue investigations are often extremely time-consuming. The results of the tests depend upon numerous factors, and therefore handbook data must include all of the parameters which affect reported test results. The calculation of fatigue life and strength cannot be performed without having appropriate information concerning the specific fatigue situation. Nor can test programs be properly prepared without knowing the service conditions and the results of previous tests as, otherwise, the results obtained cannot be generalized. Information on component fatigue behaviour is of importance not only to machine designers but also to production engineers in charge of component manufacture, since processing strongly affects fatigue strength, and to maintenance engineers in charge of the operation and repair of cyclically loaded machine elements.

Download or read book Recommendations for Fatigue Design of Welded Joints and Components written by A. F. Hobbacher and published by Springer. This book was released on 2015-12-23 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a basis for the design and analysis of welded components that are subjected to fluctuating forces, to avoid failure by fatigue. It is also a valuable resource for those on boards or commissions who are establishing fatigue design codes. For maximum benefit, readers should already have a working knowledge of the basics of fatigue and fracture mechanics. The purpose of designing a structure taking into consideration the limit state for fatigue damage is to ensure that the performance is satisfactory during the design life and that the survival probability is acceptable. The latter is achieved by the use of appropriate partial safety factors. This document has been prepared as the result of an initiative by Commissions XIII and XV of the International Institute of Welding (IIW).

Available in PDF, EPUB and Kindle. Book excerpt: These recommendations present general methods for the assessment of fatigue damage in welded components, which may affect the limit states of a structure, such as ultimate limit state and serviceability limited state. Fatigue resistance data is given for welded components made of wrought or extruded products of ferritic/pearlitic or banitic structural steels up to fy = 700 Mpa and of aluminium alloys commonly used for welded structures.

This book was released on 2013-01-25 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The weld toe is a primary source of fatigue cracking because of the severity of the stress concentration it produces. Weld toe improvement can increase the fatigue strength of new structures significantly. It can also be used to repair or upgrade existing structures. However, in practice there have been wide variations in the actual improvements in fatigue strength achieved. Based on an extensive testing programme organised by the IIW, this report reviews the main methods for weld toe improvement to increase fatigue strength: burr grinding, TIG dressing and hammer and needle peening. The report provides specifications for the practical use of each method, including equipment, weld preparation and operation. It also offers guidance on inspection, quality control and training as well as assessments of fatigue strength and thickness effects possible with each technique. IIW recommendations on methods for improving the fatigue strength of welded joints will allow a more consistent use of these methods and more predictable increases in fatigue strength.

This book was released on 2006-11-15 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: Local approaches of fatigue assessment have become an indispensable design tool for the layout and dimensioning of welded structures. This book reviews the available local approaches, the hot spot structural stress approach, the notch stress and strain approach, and the fracture mechanics approach. The presentation includes spot-welded and seam welded joints in both steel and aluminum. Examples are taken from such fields as offshore engineering, shipbuilding, structural engineering, pressure vessels, and automotive engineering. Fatigue Assessment of Welded Joints by Local Approaches is designed as a handbook for design engineers and structural analysts.
