Branagan Reliable tensile data are crucial in the automotive design process, particularly for the implementation of new Advanced High Strength Steel grades that can be used in new intricate shapes...

... forces transferred across the joint. In this research study, the leakage performance of joints in reinforced concrete, corrugated high-density polyethylene, and corrugated steel pipelines is evaluated when joints are subjected to expected service conditions. To do this, a testing apparatus...

...Tomoya Kawabata; Masahito Kaneko; Shuji Aihara To enhance the integrity of manufactured steel plate structures, the arrest toughness is an important parameter and is actually required in several structural applications, e.g., shipbuilding, tankage, and power plants, where brittle cracking occurs...

... of the use of J e for a well characterized A533B-1 steel. Tests were made at ambient temperature using geometrically scaled plain-sided and side-grooved compact C(T) specimens of sizes 20 < W < 200 mm . The fixing of A through the use of J e provides less variable α and β parameters. The exponent β...

... of this formula the activation energy of the static fatigue of glass and of the creep of steel is calculated from experimental data at different temperatures. The activation energy determined for steel corresponds to activation energy for the diffusion of sulfur in iron but corresponds also to the half...

...R Kieselbach; R Krieg The test results of a larger research project on the strain at failure for a diversity of steel specimens and parameters were evaluated with respect to the influence of the volume of the specimens. The evaluation was based on the statistical Weibull distribution. It could...

...J Qu; JJ Truhan; PJ Blau The loop abrasion test (based on ASTM G 174-03) was modified to accommodate cylindrical specimens in place of the usual flat specimens. Hardened AISI 52100 steel, a galling-resistant stainless steel (Nitronic 50), transformation-toughened zirconia ceramic, and an advanced...

... and direct measurement of the load-line displacement during the instrumented Charpy testing were conducted simultaneously on a conventional ship grade steel. V-notched and fatigue precracked test pieces were tested in the temperature range +23°C to −80°C. The results obtained with AE monitoring were compared...

... displacement derived from the load signal by double integration according to standard procedures. The ISO striker edge is instrumented with a piezoelectric sensor and the system is calibrated in situ in the impact tester as recommended by ISO 14556:2000 Steel Charpy V-notch Pendulum Impact Test—Instrumented...

...A Wolfenden; JQ Hodge Measurements were made of the density, dynamic shear modulus, damping, strain amplitude, and resistivity in iron-copper and steel-based metal matrix composites. The density was determined using the Archimedes method and was found to be in the range of 7463 to 8257 kg/m 3...

...B Yuan; WN Sharpe, Jr This paper describes a technique for measuring the strain-controlled cyclic stress-strain behavior of microspecimens taken from a steel weldment. The specimens have a cross-section 0.3 by 0.3 mm with a gage section approximately 1.4-mm long and are believed to be the smallest...

.... An alternative suggestion to control model test furnaces by heat flux instrumentation is also postulated. Finally, experiences with the application of the methodology to some wide-ranging research studies on brickwork compartment walls, reinforced concrete floor slabs, and steel columns in standard fire tests...

...WH Bailey, Jr Temperature measurements of 20-cm round, 10-m long, continuous-cast steel billets in the cooling stages of production were made using a contact thermocouple. Temperatures were measured from the time they reached the cross transfer on the cooling bed to a holding area across the street...

...S Bian; S Maj; DW Borland Previously reported studies of the unlubricated sliding of quenched-and-tempered steel pins against similarly treated rings have been supplemented by temperature measurements and tests over a range of loads and speeds. The rate of wear of a pin depends on the hardness...

... alkaline cleaning and degreasing processes leave mainly a siloxane-type of contaminant that deteriorates the adhesion of metals to epoxies. Phosphating leaves the surface clean and microrough, which improves the adhesion of adhesives to cold-rolled steel (CRS). Epoxies when cured at high temperatures give...
