End Effects in Twisted Cord‐Rubber Composites

Abstract This paper investigates the cord‐matrix load transfer problem in twisted cord‐rubber composites. The central feature of the study is to ascertain the polarizing effects of twist‐induced coupling of the axial loads and torque. Particular emphasis is given to the end problem, namely the transition between the axial‐circumferential shear stress‐dominated end region and the axial normal stress and torque‐controlled far‐from‐end zone. This is achieved through the development of both a closed form analytic formulation and its corroboration by a detailed finite element simulation.
