The Tensile Strength of Corneal Wounds
Archives of Ophthalmology, 1968The tensile strength of central and peripheral penetrating corneal wounds was measured. The gain of strength of central wounds at different time intervals was recorded up to 100 days. Peripheral corneal wounds healed faster than central wounds. Permanent closure of eye lids had no effect on the gain of tensile strength, nor did the presence of a fornix-

Tensile tests have been performed on whiskers of iron, copper, and silver 1.2 to 15 μ in diameter. The strongest whiskers which were less than 4 μ in diameter exhibited resolved elastic shear strengths of from two to six percent of their shear moduli.

In this chapter, the probabilistic porous-solid model is used to simulate the tensile strength of unsaturated soils tested at different water contents. The strength of unsaturated soils can be split into two parts: one related to the net stress and the other to suction stress.

Tensile strength of restorative resins
European Journal of Oral Sciences, 1980Abstract –The purpose of the present work was to measure the tensile strength of restorative resins and to study the effect of the method of measurement on the recorded results. A direct pull method using dumb‐bell shaped specimens was used. The tensile strength of the resins was also tested using die diametral compression method suggested by the A.D.A.

AbstractA current theory of the tensile strength of rubbers invokes large‐scale crosslink interchange at room temperature to explain the high tensile strengths of networks crosslinked with weak linkages. This mechanical lability of certain crosslinks has been assumed from their known thermal lability at higher temperatures.

Apparatus is described which has been developed for the measurement of the tensile strength of coal by bending thin strips. Measurements on four coals show that the strength depends on the type of coal and on the direction of loading relative to the bedding planes.

The tensile strength of hardmetals
Journal of Materials Science, 1979In conventional bend tests on hardmetal specimens with a rectangular cross-section the strength values exhibit a wide scatter as a result of fracture being initiated from pores and inclusions. A new bend test-piece geometry has been devised which subjects a relatively small volume of material to a high tensile stress and so reduces the probability of ...

Studies on Clot Tensile Strength
Thrombosis and Haemostasis, 1967Summary1. A technique is described for measuring the tensile strength of plasma clots.2. Platelet-induced clot retraction brings about a marked increase in clot tensile strength.3. Normal platelet levels are associated with maximal clot tensile strength. Both high and low levels of platelets are associated with reduced clot tensile strength.

Tensile Strength of Spinal Ligaments
Spine, 1988Spinal ligaments from 41 fresh human male cadavers were tested. The ligaments were tested in situ by sectioning all elements except the one under study. The force deflection curves demonstrated a sigmoidal shape, and the point at which an increase in deflection was obtained with decreasing force was taken as failure.

Tensile Strength and Friability
2000Tensile strength is defined as the stress, or force per unit area, required to cause soil to fail in tension, that is, to pull it apart. Tensile strength is remarkably sensitive to the soil microstructure, and this makes it a valuable parameter to measure in research into the structure and behavior of soil.
