The study of ABS structures in their different stages of life cycle involves taking into account several complicated phenomena. However, the effect of temperature and geometric discontinuity in the material has been identified as morphological mechanisms responsible for the deterioration of its mechanical properties. Within the framework of this problem, this study is interested in the characterization of ABS performance and the evaluation of the effect of the defect on its mechanical behavior. The influence of discontinuity in the material was assessed by a series of uniaxial tensile tests on virgins and artificially damaged specimens. Subsequently, the results of the experimental tests were used to predict the damage and the instantaneous reliability of the material as well as to find a relationship between these two parameters through the fraction of life, which makes it possible to monitor the degradation of the material and predict the moment of acceleration of the damage. This technique can provide manufacturers with a predictive maintenance strategy.

Key words: ABS, polymer, reliability, damage, life fraction, tensile tests
