Abstract

The measurement of Young's modulus, the breaking strength and the breaking index in the stretching of tissues of the dog and of humans is described. The breaking index is defined as the ratio of breaking strength to Young's modulus. These measurements were made by static determinations of the stress-strain relationship. Some twenty-three different tissues or segments of tissue were used in these tests. The results reported have an accuracy of the order of 25%. The values reported on the few samples of human tissue studied are different only to a small degree from the values found for the tissues of the dog. The values for Young's modulus ranged from 5.7 x 600 dynes per square centimeter for the transverse direction around the aortic arch to 110 x 600 dynes per square centimeter for the skin of the abdomen. The values for the breaking strength ranged from 3.3 to 44.4 kilograms per square centimeter for the same tissues. The breaking index rangee from 0.17 for the longitudinal direction of the midesophagus to 0.71 for the longitudinal direction in the same organ.
