Abstract The coil‐strand (CS) model is described. After a phase of elastic deformation of an isotropic coil a highly oriented strand and a still isotropic rest coil are formed. Entropy and several energy contributions are calculated and compared with experimental data. The constant tensile stress acting on the craze surface, the inverse relationship between fibril extension ratio and fibril volume fraction and the temperature dependence of the product of tensile stress and fibril diameter can be calculated directly from the model. Some other properties are discussed.
