39—the Stress–strain Properties of Multi-Ply Cords Part Ii. Experimental

The theory put forward by Treloar (Part I) is used to calculate the stressstrain curves of cords of 2-, 3- and 7-fold constructions. In each case this is done for one particular singles twist and a range of cord twists (including some in the same direction as the single twist). The calculated curves are then compared with the corresponding experimental curves, the degree of agreement being found to be quite satisfactory.
