Abstract:
To investigate different responses of direct and indirect tensile strengths to loading rate, direct and indirect tension tests were performed on sandstone, rust stone, and granite specimens. Typical load curves indicate that a peak tensile stress frequently appears before the second peak stress, used to calculate the tensile strength in indirect tension tests. As expected, increase in the loading rate increases the tensile strength. In addition, the calculated tensile strengths of the indirect tension tests are frequently higher. Interestingly, the increase ratio of the tensile strength with t

Abstract:
The use of high-tension bars to strengthen flexural members is gaining increasing interest. However, the applicability of current standards to such bars is uncertain, because there may not be a definite yield strength and it may be unclear whether the tensile or compressive failure mode dominates. Determining the balanced–destruction steel ratio is particularly difficult. We measure the bending behaviour of flexural members containing high-tension bars with different yield strengths and tensile steel ratios. We conclude that the maximum-steel-ratio regulation and nominal -strength equation in

Abstract:
Sandstone is widely used a construction and building material. However, its uniaxial tensile strength (UTS) is not adequately understood. To characterize the uniaxial tensile strength of natural sandstone, three groups of specimens were fabricated for four-point bending, uniaxial compressive, and tensile tests. To characterize the evolution of the stress–strain profiles obtained via these tests, representative expressions were developed in terms of normalized strain and strength. The magnitude of the uniaxial tensile strength exceeded that of the four-point bending strength, indicating that th

Abstract Effects of H2S concentration and temperature on sulfide stress cracking (SSC) of fine grained 110 ksi (758MPa) grade steel for OCTG compared with API L-80 and C-90 were examined in the NACE solution by means of slow strain rate technique (SSRT) test. The susceptibility to SSC increases with increasing H2S concentration and typical features of cleavage fracture are observed by hydrogen embrittlement. The fine grained 110 ksi (758MPa) grade steel shows the best resistance to SSC in terms of ultimate tensile stress (UTS), and intergranular cracking of this steel is not observed. The 110

Abstract In this paper, the Young's modulus, Poisson's ratio, and ultimate tensile strength of HVOF-sprayed NiCr (80/20) coating are evaluated by a uniaxial tensile test parallel to the coating plane. The effect of stand off distance is also considered. It is observed that, in the tensile test, the alloy NiCr (80/20) showed moduli of elasticity between 130 and 155 GPa and tensile strengths between 185 and 210 MPa. For the WC-CoCr alloy, the modulus of elasticity was between 185 and 210 MPa and the tensile strength was around 80 MPa. Paper includes a German-language abstract.

Abstract:
It is well known that both the yield strength and the tensile strength of a material have significant effect on the failure behavior of pipelines. Thus it can be anticipated that the yield-to-tensile strength (Y/T) is closely related to the strain hardening behavior of the material, and it also influences the failure behavior. This paper theoretically explores the influence of T/Y (the inverse of Y/T) ratio on the failure pressure of pipelines with or without corrosion defects. Based on the instability of deformation and finite strain theory, a plastic collapse criterion for close-ended pipes

Abstract Upper limits on the ratio of the yield strength to the tensile strength (σy/σu ratio) and lower limits on the fracture elongation εf are present in various offshore, maritime and civil engineering rules, standards and specifications for steel structures as a provision for the minimum material ductility and toughness which ensures sufficient structural ductility. In other instances, the design yield stress to be adopted in strength calculations is reduced from its nominal value if the σy/σu ratio exceeds a certain limit. Such requirements deter the use of high strength steels (nominal

The increased demand for high strength linepipe for onshore and offshore pipeline systems has been well documented over the past few years. The economic benefits have been demonstrated, and solutions have been developed to address the technical issues facing high strength linepipe use. However, there are still a few unanswered questions, one of which is addressed in this paper: what is the effect of thermal treatment during the pipeline coating process on the material behaviour of high strength linepipe?

Abstract:
Considerable research has been conducted to define the significance of the yield-to-tensile (Y/T) ratio for line-pipe steels. In the late 1960s and early 1970s, a study was completed in which a series of burst tests was conducted on 41 pipes ranging from 8 to 42 inches in diameter and representing API Specification 5L Grades A through X65. In this study, only 2 of the 41 materials studied had a yield-to-tensile ratio greater than 0.9, and these were artificially created. With the advent of the X70 and X80 steels, higher yield-to-tensile ratios have developed as the yield strength increased. A

Abstract:
Micro-alloyed low-carbon linepipe steels offer an advantageous combination of high toughness and a low carbon equivalent (CE or Pcm) for good weldability. The continuing improvements in pipeline steel manufacturing practices have also led to pipeline steels with higher yield to tensile (Y/T) ratios and a corresponding reduction in strain hardening capacity. Potential users of high Y/T ratio pipeline steels are somewhat reluctant to modify their existing specifications. This is because they do not have the required information to judge the performance characteristics of such steels under a wide

Although current manufacturing methods result in highly reliable welds in ERW pipe, occasional small bond line defects, difficult to detect with present nondestructive test techniques, still are found. The development of improved inspection techniques to permit the detection of such small defects is a difficult undertaking. An Alternative approach toward increasing the reliability of ERW pipe is to insure that the weld region is able to tolerate the presence of any undetected defects without failure, that is, to insure that the weld has adequate ductility.

Transportation has an enormous impact on the U.S. economy and on the lives of all Americans. Many modes of transportation rely on pavement, but pavement conditions deteriorate over time because of the combined effects of traffic and climate. Exposure to moisture often causes premature failure of asphalt pavements as it reduces the stiffness of the asphalt and enables stripping of the asphalt from the aggregate. This research evaluates the effectiveness of clay nanomaterials (i.e., nanoclays) in improving the resistance of hot mix asphalt (HMA) to moisture damage and compares the enhancement re

Abstract:
Much of the design, construction, and maintenance practices in the pipeline industry was established before the extensive use of modern control-rolled and microalloyed steels. These modern steels can behave differently from traditional hot-rolled and normalized steels. For instance, these modern steels tend to have a lower strain hardening capacity (higher Y/T ratio) than vintage hot-rolled and normalized steels. One of the observed trends is that modern steels could be qualified as higher grade due to the increase of yield strength (YS) while their ultimate tensile strength (UTS) remains at a
