      <title>EVALUATION OF STRAIN MEASUREMENTS FROM TESTS WITH BEAMS ORE D 130</title>
      <link>https://trid.trb.org/View/15524</link>
      <description><![CDATA[The report deals with the analysis of strain measurements on both I and box girders butt-welded mid-beam and provided with various welded attachments on the flanges and webs. The problem is whether it is possible to predict yield strength when the local strain ranges near stress concentration points susceptible to fatigue fracture are measured with suitably arranged strain gauges.]]></description>

      <title>FATIGUE PHENOMENA IN WELDED CONNECTIONS OF BRIDGES AND CRANES</title>
      <link>https://trid.trb.org/View/15525</link>
      <description><![CDATA[The report presents the results of a statistical analysis of all the fatigue tests carried out by the Committee Members using the method of maximum likelihood.  Design procedures for the principal types of welded connections used in bridge work are outlined together with recommendations for their application to the weldments of smaller structures.  The report also includes the method of dealing with the variable amplitude loading experienced by bridge members under service conditions, using the rain-flow method of cycle counting and the Palmgren-Miner hypothesis of cumulative fatigue damage.]]></description>

      <title>FATIGUE PHENOMENA IN WELDED CONNECTIONS OF BRIDGES AND CRANES. TESTS WITH SMALL I-BEAMS WITH A LOW STRESS LOAD SPECTRUM</title>
      <link>https://trid.trb.org/View/15521</link>
      <description><![CDATA[This report contains a description of the results of 3 tests, carried out on small I-beams with welded-on stiffeners under spectral load.  Plates are welded on the compression flange in the longitudinal and lateral directions.  Two sources of fatigue strength data and the maximum likelihood method were used to analyse the results. The available data did not suffice, however, to determine differences between the fatigue strength curves.]]></description>

      <title>FATIGUE PHENOMENA IN WELDED CONNECTIONS OF BRIDGES AND CRANES. GRAPHICAL AND ANALYTICAL EVALUATION OF FATIGUE STRENGTH DATA FOR WELDED CONNECTIONS</title>
      <link>https://trid.trb.org/View/15478</link>
      <description><![CDATA[Results of fatigue tests are evaluated on a uniform basis, using the normalised Wohler line for welded joints in structural steel.  The graphical method hitherto used and a newly developed analytical method are applied, both methods being described.  The investigations refer to bar-like specimens and specimens resembling structural members. Significant statements concern: the slope of the Wohler line, the scatter of stresses and endurances, the cut-off of the Wohler line.  The results of both methods differ to some extent.  A comparison with other results has been included.]]></description>

      <title>APPLICATIONS OF FREQUENCY ANALYSIS IN ULTRASONIC TESTING</title>
      <link>https://trid.trb.org/View/72084</link>
      <description><![CDATA[Applications and theory associated with control of ultrasonic test variables, identifying and sizing flaws, and improving resolution both for thickness measurements and detection of near-surface flaws are presented.  The advantages of spectral analysis techniques in reproducibility, precision, simplicity, and evaluation of importance of discontinuities in materials are discussed. Examples of discontinuity spectra for welds are shown in graphic form with the corresponding oscillographs.]]></description>

      <title>SETTING OF SENSITIVITY OF ULTRASONIC EQUIPMENT FOR WELD INSPECTION</title>
      <link>https://trid.trb.org/View/72087</link>
      <description><![CDATA[The disadvantages of current methods of setting sensitivity of ultrasonic equipment for weld inspection and the work put forth by the author in connection with overcoming these disadvantages are discussed.  The approach utilizes commonly used ultrasonic equipment and a variety of grease-coupled probes.  The author's work leads to putting forward a general formula for sensitivity in terms of the amplitude from a reference hole on a 11W block and the attenuation. Working examples and practical advice to the operators is given.  The application of Krautkramer Types USK5 and USM2 test equipment is described in this article.]]></description>

      <title>EXPERIMENTAL INVESTIGATION OF RESIDUAL WELDING STRESSES IN ELEMENTS OF THE FRAME OF BOGIES OF ROLLING STOCK</title>
      <link>https://trid.trb.org/View/13096</link>
      <description><![CDATA[Unfavorable residual stresses, reaching the yield point, may develop in welded elements of bogie frames of rolling stock.  Considerable reduction of these stresses, as a result of tempering, to the value 350 kgf/sq cm, should promote an increase of service reliability of the bogie frames.]]></description>

      <description><![CDATA[This report summarises conclusions from previous static and fatigue tests on welded connections, and describes further such tests on connections modified in attempts to mitigate the weaknesses of the original two types, both by thickening the material and by stress relieving notches.  Photo-elastic tests contributed to the latter study.  Appendices give laboratory reports and notes on statistics.]]></description>

      <link>https://trid.trb.org/View/18112</link>
      <description><![CDATA[The report describes fatigue tests on large butt-welded beams and concludes that strength is lower than would be predicted from results using small specimens, or from many codes of practice.  Tests incorporated shop and site welds and attachments provoking local stress concentration.]]></description>

      <title>ASSESSING THE SIGNIFICANCE OF FLAWS IN WELDS SUBJECT TO FATIGUE</title>
      <link>https://trid.trb.org/View/24908</link>
      <description><![CDATA[The substitution of fracture mechanics crack propagation data for simple S-N curves provides additional data on welds defects, other than applied stress and the influence of geometry.  It allows the fatigue process to be entered (variation in initial flaw size) and left (variation in failure criterion) at will and variations in geometry and crack share to be taken into account.  The value of the method has been confirmed by accurately predicting the fatigue behavior of fillet welds containing flaws on the basis of the generalized stress parameter.]]></description>

      <title>EFFECT OF PRE-AND POST-HEATING ON WELD CRACKING OF LOW ALLOY STEELS</title>
      <link>https://trid.trb.org/View/38801</link>
      <description><![CDATA[The results indicate that cold cracking cannot occur at the temperature above the critical point, which is 80deg C in the case of HT80 steel joint; the delayed cracking may occur at low temperatures; the activation energy determined by incubation time of delayed cracking is 11,000 cal/mol at the temperatures over-30deg C and 2300 cal/mol below -30deg C, the activation energy determined by the effect of postheating on the cracking is 13,000 cal/mol independently of steel grade, and the preheat temperature may be reduced by using postheating, but thermal stress cracking may occur under certain conditions under which blue brittleness or precipitation brittleness takes place.]]></description>

      <title>EFFECT OF MACHINE RIGIDITY AND LOAD APPLICATION RATE ON THE STRESS-STRAIN BEHAVIOR OF WELDED JOINTS OF HIGH-STRENGTH STEELS</title>
      <link>https://trid.trb.org/View/38607</link>
      <description><![CDATA[An experimental program has been carried out with the aim to determine the effect of the testing machine for static tensile tests and the load application rate on the fracture behavior of welded high-strength steel.  In addition to conventional universal hydraulic testing machine with "soft" characteristics, a servohydrualic and a thermally controlled testing machine with "hard" characteristics have been employed for this purpose.  The latter machines made it possible to conduct control tensile tests which enabled the deformation behavior to be expressed as a function of the load application rate.]]></description>
