What is Factors Affecting Stress Transmission in Crystalline Polymers about?
## Abstract The paper is concerned with stress transmission in and around the molecular ties which connect lamellae in many semicrystalline polymers. Assuming a continuum model, finite element calculations have been performed to investigate stresses and displacements for a cylindrical tie embedded in a sheath of lamellar crystal. Two specific cases were studied: the single‐ended case where the tie enters the lamella from one side only, and the double‐ended case where it passes right through the lamellar crystal. Elastic constants for crystalline polyethylene were assumed, and a variety of different geometries were investigated, corresponding to single‐chain or multichain ties with sheaths of various diameters. The finite element study confirmed that the distance for stress diffusion from the tie into the lamellar sheath can be quite large, and that there are significant displacements due to tensile deformation of the tie within the crystal and shear deformation of the lamellar sheath. An interesting feature in the case of multichain ties is that tensile stress is concentrated around the outer surface of the tie. An analytical model is proposed, based upon shear lag theory.
