Abstract

The yield stress anisotropy of rolled polyoxymethylene (a semicrystalline polymer) is predicted by treating the polymer as a polycrystalline aggregate having two types of crystal slip system. The model first predicts the texture development on cold rolling, then the angular variation in yield stress for various uniaxial stress and plane strain compression tests. At present the model has four disposable parameters (the critical resolved shear stresses for chain and prism slip, a strain hardening coefficient and a minimum yield stress on reverse yielding), which are amenable to experimental confirmation.
