Available in PDF, EPUB and Kindle. Book excerpt: Dynamic tension tests and static tension tests were conducted on four grades of structural steels. The steels conform to ASTM grades A36, A242, A441, and A572. Stress-strain curves are presented for each steel at various strain rates, ranging from static to about 1.5 in./in./sec. While all steels showed an increase in yield stress with increasing strain rates, the A36 steel showed the greatest increase. Design recommendations are given for structural steels subjected to high strain rates. Additional specimens were strain aged, and stress-strain curves were obtained for both dynamic and static tests. Of the strain-aged steels, only the A36 steel showed a significant increase in strength over the non-strain-aged steels, when loaded dynamically. No adverse effects of strain aging were noted on any of the steels. (Author).

Book excerpt: Results of tension tests on specimens machined from a specially fabricated high strength reinforcing steel are presented. Yield stress of the steel was determined over a range of strain rates from the static value of 7 x 10 to the -6th power in./in./sec up to a maximum dynamic strain rate of 0.375 in./in./sec. The % increase in yield stress for a given dynamic strain rate is computed from the ratio of the yield stress obtained at the dynamic rate to that obtained at the static rate. The % increase in dynamic yield stress for the high strength steel is lower than that previously reported for conventional reinforcing steels. Compared with static test results, the dynamic loading on high strength steel resulted in little increase in ultimate strength and no discernible change in reduction in area or in percent elongation at rupture. Dynamic tests were conducted on two types of machines hydraulic and pneumatic - to provide information about the operating characteristics of the machines. This information was used to formulate the specifications for a dynamic testing machine.

This book was released on 2003-07-01 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: The capability to conduct dynamic tensile testing of sheet steels was established and the influence of strain rate on strengthening mechanisms in sheet steels was investigated in this work. Several different automotive sheet steels were studied, including interstitial free (IF) steel, high strength low alloy (HSLA) steel, dual phase steel and transformation induced plasticity (TRIP) steel.

This book was released on 1965 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the research project was the development of modelling techniques for steel structures and an investigation of the effect of strain rate on the resistance function of structural elements. The work proceeded in four phases: a dynamic loading machine was developed, dynamic material properties were determined in a series of tensile tests, 16 static and dynamic tests were performed on simply supported beams loaded at the third points, and a series of 16 static and dynamic tests were performed on fixed ended portal frames subjected to a lateral load at the level of the girder. The dynamic loading machine is capable of rise times of 3 milliseconds or more and maximum loads of 2000 pounds. It can also be used as a static loading machine. Generally, it is concluded that model studies of steel structures provide an excellent experimental tool. Very sensitive tests for the investigation of strain rate effects have been developed. The necessary apparatus and techniques have been refined and initial difficulties eliminated so that a large number of additional tests on models with a variety of geometric configurations and material properties could be performed rapidly and reliably. These tests might significantly extend our understanding of the dynamic behavior of steel structures. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The Report provides comprehensive toughness criteria for welded ship hulls that can be used for steels of all strength levels. Because of the fact that stress concentrations are always present in large complex welded structures and therefore high stresses as well as discontinuities or flaws will be present in welded ship hulls, primary emphasis in the proposed fracture-control guidelines is placed on the use of steels with moderate levels of notch-toughness and on the use of properly designed crack arresters. In general, concepts of fracture mechanics are used to develop the material toughness level that is required for fail-safe operation of welded ship hulls.
