Effect of Metal Impurities on the Tensile …
Metal catalysts used in the synthesis of carbon nanotubes (CNTs) are one of the main impurities in CNT fibers. Using quantum mechanical computations, we show that these metal impurities have a large impact on the mechanical performance of CNTs and CNT fibers. One single Ni atom adsorption on the wall of a single-walled CNT (SWCNT) can decrease the tube's critical strain about 40% by ...

Effect of Aggregate Properties on the Crushing …
This paper studied the effect of aggregate properties on the crushing strength of concrete. In order to achieve the study objective, three types of coarse aggregates, brick khoa, shingles stone, and black stone were used to test. And the test results show that concrete made from black stone has the highest workability followed by shingles stone & brick khoa of aggregates.

Size and Shape Effects on the Compressive Strength of High ...
The strength obtained with this specimen is higher in average than that obtained with 150 £ 300mm cylinders. This size effect on the compressive strength manifests that the specimen is not behaving as simply as it may look. Indeed, size effect is understood as the dependence of the nominal strength of a structure on its size (dimension) when

Effect of Sulphur in Carbon Steel
I am sure we are indebted to Prof. Hayward for his addition to our knowledge of the influence of sulphur on steel. As he has said in this paper, sulphur has had many defenders in recent years. It seems to me, however, that, while it may be old school to believe in the detrimental action of sulphur, it is not yet old school to believe in segregation; that while it may be that 0.1 per cent, of ...

The effect of impurities and strength level on …
Abstract The effect of impurities on the threshold stress intensity for cracking in H 2 S (K{ISCC}) has been investigated at various yield strength levels for a low alloy steel. Results show that the effect of impurities on K ISCC is a function of the yield strength level. At low yield strength levels the K ISCC of the steel is lowered markedly due to additions of impurities.
