Summary:The equations in this paper determine the kinetics of elastic deformation in polymeric films under loading to the point of destruction. The rheological model indicates that the destruction of polymeric films is characterized by relaxation time, initial stress and the level of limited deformation. These results make it possible to determine the critical time and allow prediction of the performance of this product. The destruction of polymeric films can be calculated from the results presented herein and only requires evaluation of the accumulated elastic deformation for each discrete load. The period of time after which the accumulated elastic deformation from discrete loading reaches a critical value provides a theoretical estimate of product life. This paper proposes a reasonable agreement between experimental data and model prediction.
