In this paper, we describe an experimental study of concrete behavior under a uniaxial tensile load by use of the thermally-compensated Coda Wave Interferometry (CWI) analysis. Under laboratory conditions, uniaxial tensile load cycles are imposed on a cylindrical concrete specimen, with continuous ultrasonic measurements being recorded within the scope of bias control protocols. A thermally-com...

Stretch-flangeability measures the ability of a material to form into a complex shape. The parameter is often related to simple properties derived from tensile tests. An attempt is made here to discover the best way to exploit tensile test data to indicate flangeabilty. It is found that the ultimate tensile strength of steel is the single most important criterion that correlates with stretch-fl...

Using natural hemp fibers to reinforce the tensile characteristics of polymer matrix composites is investigated in this article. The fibers were applied to the epoxy matrix in unidirectional and hybrid tissue forms. After preparation of standard tensile stress test specimens via manual layup, the standard tensile test was done.  Young’s modulus, ultimate tensile stress, and the amount of absorb...

A bulk nanocrystalline Co–P alloy was subjected to tensile tests. Grain growth from approximately 12 nm in the as-deposited state to about 25 nm after the tensile test was observed. Grain growth was not observed when the deforming volume was increased, or when the specimen was annealed at 433 K or above prior to the tensile tests. 2006 Acta Materialia Inc.

Tensile strength is one of the important strength parameters of concrete. Indirect methods have been used up till now for its measurement. These methods though widely accepted, do not furnish the true tensile strength of concrete. This paper presents a new approach for the experimental determination of true tensile strength of concrete. Results obtained by this test are quite encouraging and sh...

The penetration coefficients (PC) and tensile bond strengths of two pit and fissure sealants and a low viscosity bonding resin were evaluated. The penetration coeftYcients of the resin systems were determined at 22°C. Five determinations were done with each resin. Bonded test specimens were loaded to failure in the tensile mode in an Instron testing macl~’ne. Ten specimens were prepared with ea...

Experimental study on the influence of fibre content on crack behaviour and propagation in synthetic-fibre reinforced beams has been reported in this paper. The tensile behaviour of metallic fibre concrete is evaluated in terms of residual flexural tensile strength values determined from the load-crack mouth opening displacement curve or load-deflection curve obtained by applying a centre-point...

In Malaysia, there is no research done on the tensile strength of structural size timber. The tension stress found in the Malaysian code of practice, MS 544: Part 2: 2001, was not determined directly and it was taken as 60% of the bending strength values of small clear specimens. This paper presents the results of the tensile test on structural size timber specimens from selected Malaysian Trop...

Results The USP Class I Min. Avg. 2-0 Suture Knot-Pull Tensile Strength (Doubled for Loop Test) is defined as 2.88 kgf. The Tensile Strength of Lot # 1-9364 was 4,7761 ± 0,2005 kgf (mean ± std dev) min 4.2282, max 5.2289, and for Lot # 1-9364 was 5,5151 ± 0,2625 kgf (mean ± std dev) min 4,0044, max 5,1356, respectively. There were no statistically signiffcant differences between the both lots (...
