Tensile
Definition:

(a.) Capable of extension; ductile; tensible.
Example Sentences:
(1) Experiments have been performed using CO2 laser-assisted microvascular anastomoses, and they demonstrated the following features, in comparison with conventional anastomoses: ease in technique; less time consumption; less tissue inflammation; early wound healing; equivalency of patency rate and inner pressure tolerance; but only about 50 percent of the tensile strength of manual-suture anastomosis.
(2) A logarithmic relationship between closing tension and tensile strength was demonstrated using linear regression analysis with t = 6.18, p less than .0001, and R2 = .44.

(4) Therapeutic doses of cHyp in liposomes injected for 6 months affected tensile properties of main pulmonary artery and aorta, but there were no apparent histological effects on other organs.
(5) After the tensile test the residue of the bonding agent on one surface of the test-piece pairs, always remained significantly higher, than on the other, but this phenomenon cannot be explained by the differences between R(a) and Rmax within the test-piece pairs.
(6) Alternatively, a loss of collagen tethers or decline in matrix tensile strength can be responsible for regional or global transformations in myocardial architecture and function seen in the reperfused ("stunned") myocardium and in dilated (idiopathic) cardiopathy.
(7) Proof stress, ultimate tensile strength, elongation, and plastic stiffness have been measured and results compared by use of analyses of variance.
