On the tensile strength of insect swarms [PDF]

open access: possiblePhysical Biology, 2016
Collective animal groups are often described by the macroscopic patterns they form. Such global patterns, however, convey limited information about the nature of the aggregation as a whole. Here, we take a different approach, drawing on ideas from materials testing to probe the macroscopic mechanical properties of mating swarms of the non-biting midge ...

The Tensile Strength of Elastomers

Rubber Chemistry and Technology, 1955
Abstract The theory of strength proposed above appears to describe satisfactorily the effect of crosslinking on the strength of amorphous elastomers, and to apply semiquantitatively to crystallizable elastomers. Further work, involving the effect of primary molecular weight, constitution, swelling, and additives is required to ...

The Tensile Strength of Benzene

The Journal of Chemical Physics, 1951
Measurements were made of the tensile strength of benzene, by the centrifuge method. The method is described, together with various features which have been incorporated into the procedure to insure uniformity of samples. There is evidence, which is not conclusive however, that the rupture strength increases as the amount of permanent gas dissolved in ...

THE TENSILE STRENGTH OF PORCELAIN1

Journal of the American Ceramic Society, 1922
A method of accurately determining the tensile strength of porcelain has been developed. The ratio of tensile to compression strength was found to be 5.9 for the special porcelain studied. Triaxial porcelains gave an average ratio of 7.66. The tensile strength tests show in general a little more variation than compression strength tests.

Tensile Strengths and Hardness of Tablets

Journal of Pharmaceutical Sciences, 1982
The axial and radial tensile strengths were compared to the hardness of compressed tablets containing various concentrations of lubricants. Since radial tensile strength measurement considers the thickness of a tablet, and only tensile stress and axial tensile strength express the strength in the direction in which capping may occur, the tensile ...

The tensile strength of composite repairs

Journal of Dentistry, 1980
Abstract The interfacial (bond) strength established between composite additions and recently set composite or matured composite (of the same type) has been determined by means of tensile fracture stress. Five different composite products were selected for examination, which covered the variety of matrix compositions available today.

Tensile strength of water

Nature, 1979
THE measured tensile strength of water has long been known to be significantly less than theoretical predictions and the reduced strength is normally attributed to the presence of solid impurities that serve as nucleation sites for rupture of the liquid1.

Tensile Strength of Asbestos

Nature, 1959
ASBESTOS is the generic name for those silicate minerals which cleave naturally into fibres, the three important species being chrysotile (white asbestos), crocidolite (blue asbestos) and amosite. This unique mineral structure lends itself better to measurements of tensile strength than do the more common minerals with isotropic or platy structures ...

Tensile Strength of Unsaturated Soils

Soil Science Society of America Journal, 1985
AbstractA better understanding of the nature of tensile failure in unsaturated soils is important if adequate theories explaining the behavior of soils under tillage or during processes such as frost heaving are to be developed. In this paper, the problem of tensile failure of uncemented soils is formulated by combining Aitchison's extension of the ...

The tensile strength of rocks

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1964
Abstract Results are given of tensile strength measurements made on rock using the diametrical compression of a disk with a central hole as a technique for determining tensile strength. Detailed quantitative information of the variation of the tensile strength with lamination orientation is given. It is shown that a relationship may exist between the
